What else can I help you with?
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
Can you provide some right-hand rule practice problems?
Here are some practice problems for the right-hand rule: Determine the direction of the magnetic field around a current-carrying wire using the right-hand rule. Use the right-hand rule to find the direction of the force on a charged particle moving through a magnetic field. Apply the right-hand rule to determine the direction of the induced current in a coil when the magnetic field changes. Use the right-hand rule to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field. These practice problems will help you reinforce your understanding of the right-hand rule in various scenarios.
How do you find current if the resistance is not given?
You can find the current by using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). If the resistance is not given, you will need to know the voltage and another parameter such as power (P) or conductance (G) to calculate the current. Alternatively, you can measure the current using an ammeter in a circuit.
What are the key differences between the Biot-Savart Law and Ampere's Law in the context of electromagnetism?
The key difference between the Biot-Savart Law and Ampere's Law is that the Biot-Savart Law is used to calculate the magnetic field produced by a current-carrying wire at a specific point, while Ampere's Law is used to find the magnetic field around a closed loop due to the current passing through the loop.
What law is used to find the polarity of a circuit?
It is possible that Kirchoff's law will answer this question. But why make it hard? It is customary to find the polarity of a circuit by simple inspection. Let's do a basic circuit and see how it works. Draw a square. Put a battery in the left side, and put the positive terminal down and the negative terminal up. Put a resistor in the right side. Two components - a simple series circuit. The battery will be "sending out" electrons from the negative terminal (the top one), and it will be "collecting them in" at the positive terminal (the bottom one). Put a "-" by the top of the battery to label that terminal. Now put a "+" by the bottom terminal. You've specified the polarities. Anyone looking at the circuit now can "find the polarity" of the circuit by inspection. Let's go one step farther. The electrons will be flowing out the top of the battery, and over and down through our resistor. Then they'll flow out the bottom of the resistor and across and into the bottom of the battery. Very simple, very easy. Now focus on this. The polarity of the voltage drop across the resistor is negative on the top and positive on the bottom. The end of the resistor into which current flows is said to be the negative end of the component, and the end out of which the electrons flow is said to be the positive end. Is this clear? Electrons flow out the negative terminal of a battery, and electrons flow into the negative end of our resistor. Be super clear about this. That's the way voltages are labeled in a circuit diagram. (The resistor "drops" voltage, while the battery represents a voltage "rise" in circuits.) For our circuit, the voltage drop across the resistor, which can be though of as the measure of voltage across the resistor, is negative on top and positive on the bottom. If you were going to measure the voltage drop across the resistor, the black meter lead would be on top of that resistor and the red lead would be on the bottom. If anyone encounters the circuit, the polarity will be obvious by inspection. We must be given a voltage somewhere, or we must be given a direction of current flow so we can make our inspection and determine polarity. If we were given nothing about our circuit except the direction of current flow, we'd know the rest by inspection. Take the simple circuit we made and take off all references to polarity. Now draw an arrow parallel to the top line of the circuit, and make it point to the right. If that arrow represents the direction of current flow, it would be telling us current was flowing clockwise around our square circuit. The polarities of all the other components (there are only two) would then be known. We would know by simply looking at the circuit what was happening, know by inspection. [This answer has a couple of simplifications, but not where it makes any difference. The answer was designed to supply fundamental knowledge or introductory information. It is unnecessary to say, for instance, that modern digital multimeters (DMMs) will measure voltage no matter what lead is placed where - the only difference being whether on not the "minus" sign appears on the DMM's display. Save that for later. We're keeping this simple.]
What rule is applied to find the polarity of the face of a current carrying circular coil?

Where is the solenoid wire on a 1996 dodge stratus 5 speed?
Dodges and Chryslers mayby Plymouths also use a thick brown wire from the statrer relay in the fuse box. There should be two clicks by statring. Solenoid a louder and a relay a softer click. It is possible for the relay to click but its electical connection pole points might be corroded at the solenoid or the relay at the fuse box make sure that the brown wire from the relay to the starter solenoid is connected at the solenoid cleanly and tightly. If you always hear the loud click however, then you know the solenoid is getting the current from the relay and it is not applying the high current to the starter motor windings or the windings or brushes in the motor are bad, or the wire that brings the high current directly from the battery to the solenoid is loose at the solenoid. So when you find the starter make sure that the thick battery wire connection to the solenoid is clean and tight, and if it nonetheless clicks then there is indeed a problem internally with the solenoid switch or the motor proper. You can also bypass the solenoid and see if the starter cranks, to see if a problem at the solenoid.
Which table in BS 767112008 applies to the current carrying capacity of flat twin and earth cable?
The tables within Appendix 4; "Current-carrying capacity and voltage drop for cables and flexible cords." 4D1 to 4J4. For each type of cable, you will find (with a couple of exceptions) a Table A for current-carrying capacity values and following it, a Table B for voltage drop values.
Where can you find the solenoid sensor in my Chrysler 300c?
There are sensors and solenoid all over the vehicle.There are sensors and solenoid all over the vehicle.
How you can find positive and negative in a transformer?
There is no positive and negative on a transformer. Transformers will only pass AC (alternating current), due to the fact that induction will only occur with a moving field. The current has to be changing polarity and intensity continuosly, for the current to be induced in the windings. Both terminals on the output vary, with relation to each other. Put DC into a transformer and the coils will saturate, overheat and probably burn out.
Where can one find more information about plastic solenoid valves?
One can find information about plastic solenoid valves from a variety of places. Norgren, Reef Central, Danfoss, and GlobalSpec provide information about plastic solenoid valves.
How do you find solenoid on yard pro riding mower?
I assume you are talking about the starter solenoid: Follow the positive battery cable from the battery - the other end will be connected to the starter solenoid.
What is polarity test and continuity test?

In electric terms what do the abbreviations AC and DC mean?
Its Alternate Current and Direct Current. I believe Angus Young got the idea for the band name when he say AC/DC on the bottom of his sisters sewing kit. Electric current can be direct current (DC) or alternating current (AC). Direct current such as the power from dry cells is characterized by a uniform direction of flow and amount (voltage) of electricity.
Where is the solenoid located on the motor of a yard machine lawn mower?
Assuming you are referring to the starter solenoid, the easiest way to find it is by folowing the positive battery cable from the battery. The cable goes from the battery to the solenoid and then continues from the solenoid to the starter.
How can calculate the current capacity of 2.5 sq mm wire?
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.
How do you measure electrical current?
Electric current is measured using an instrument called an ammeter. The SI unit of measurement for current is the ampere, which is defined in terms of the force between parallel, current-carrying, conductors due to the interaction of their magnetic fields.
