How is it used in determining the direction of the magnetic field around a conductor carrying current?
By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.
If you ever get caught in a rip current you should swim?
You should avoid them because they are dangerous. They are able to pull you into the ocean and tire you out.
When using kirchhoffs current law if negative answer is found for current flow what does this indicate?
A negative answer in a Kirchhoff's Current Law calculation indicates that the assumed direction of current flow was incorrect. It suggests that the actual direction of current flow is opposite to the assumed direction. Therefore, the sign of the calculated current should be corrected to reflect the actual flow direction.
What should you do to verify the direction of the induced current in a circuit?
To verify the direction of the induced current in a circuit, you can use the right-hand rule. Point your right thumb in the direction of the changing magnetic field and curl your fingers. The direction your fingers curl will indicate the direction of the induced current.
Does an ammeter have a positive and negative terminal?
Yes, an ammeter typically has positive and negative terminals, which are used to indicate the direction of current flow. When connecting an ammeter in a circuit, the positive terminal should be connected to the more positive point in the circuit, while the negative terminal should be connected to the more negative point. This ensures accurate readings of the current flowing through the circuit. However, some ammeters can measure current in either direction without damage, depending on their design.
The polarity of an eletromagnet is determined by the?
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.
When capsized and floating on your back in a swift current in which direction should you point your feet?
Point your feet downstream to avoid getting them caught on any obstacles. This position allows your body to be pushed through the current feet-first, reducing the risk of entrapment. Practice floating on your back in a safe environment to increase your comfort and proficiency.
How many flares are needed for truck emergency?
If on a roadway where traffic is flowing only in one direction, you should use at least three to the rear of the vehicle. If on a two-lane road, at least three in each direction.
What is the terminal voltage using the Kirchoff's law?
current flowing into the node are taken to be negative, and currents flowing out of the node are positive. It should not really matter which you choose to be the positive or negative current, as long as you stay consistent. However, it may be a good idea to find out the convention used in your schema
What is the current flowing to a 9.5kW instantaneous electric shower fed by a 240 volt supply?
40 amps The formula you should be using is I = W/E.
How does the flow of current within the simple cell differ from that in a copper wire?
One terminal of a cell or battery is positive, while the other is negative. It is convenient to think of current as flowing from positive to negative. This is called conventional current. Current arrows in circuit diagrams always point in the conventional direction. However, you should be aware that this is the direction of flow for a positively-chargedparticle.In a copper wire, the charge carriers are electrons. Electrons are negatively-charged and therefore flow from negative to positive. This means that electron flow is opposite in direction to conventional current.
How should the direction of the magnetic field be determined at every point?
To determine the direction of the magnetic field at any point, you can use the right-hand rule. Point your thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field.
