Why does the voltage remain constant in a parallel circuit?
The answer comes from Energy Conservation Principle which commonly is known as Kirchoff's Voltage Law.Voltage is basically work done per unit charge and work is form of energy which has to be conserved. Also, electric fields are conservative that means work done depends only on initial and final points.Combining all that I have said, if you make your starting and end point same, that is run in a loop, effectively work done will be zero (Potential difference is zero). Thus in a parallel circuit if the voltages are not equal, changing the loops will violate this principle.Let's say you have 2 resistors in parallel attached to a battery. If you assume that the voltages of branches are different, then considering the loop that contains both the resistors and applying KVL violates energy conservation and that's not possible. Thus the only possibility is the voltage has to be same.Additional Note: The same voltage might not be equal to battery voltage if there is any resistor in path of parallel wires and battery. But the parallel voltages will be equal.
Why does velcro wear out?
Velcro can wear out over time due to several reasons, including frequent use, exposure to dirt and debris which can clog the hooks and loops, and damage caused by pulling or stretching the material. The hooks may become bent or broken, reducing their ability to grip the loops effectively.
Would spinning the loops on an electromagnet make it stronger?
Spinning the loops on an electromagnet will not make it stronger. The strength of an electromagnet depends on factors such as the number of loops in the coil, the current passing through the coils, and the core material used in the electromagnet. Spinning the loops will not change these factors.
What would not affect the strength of an induced current?
The strength of an induced current is not affected by the resistance of the circuit it flows through. The factors that affect the strength of an induced current are the rate of change of magnetic flux, the number of loops in the coil, and the material of the coil.
What happens as you increasse and decrease the number of loops in an electromagnet?
Increasing the number of loops in an electromagnet strengthens the magnetic field produced, resulting in a stronger electromagnet. Conversely, decreasing the number of loops weakens the magnetic field, making the electromagnet less strong.
Can a circuit be a combination of series connections and parallel conections?
Yes. There are also more complicated circuits, that can't be described ONLY as a combination of series and parallel circuits - basically, circuits that contain several loops.
How can transistors act as amplifiers or switches?
by creating two circuit loops
What is a series electrical circuit and parallel electrical circuit?
A series circuit is an electrical circuit that has all the components in one section> A Series Circuit>(Below)5A Parallel Circuit is an electrical circuit that has a main section, plus additional branches for components, so that the current can be dispersed. If the power is dispersed, than the components get a larger current of power, leading them to perform at a higher quality.(This is a parallel circuit... Except that a parallel circuit is connected.)5?5 I hope I answered your question!JSigned: Mihali8
How are series circuits and parallel circuits?
A parallel circuit is used in a strand of Christmas lights so that if one bulb goes out, the rest don't. A parallel circuit is also used in circuit breakers of houses. A series circuit is used in a flashlight. Everything follows one path.
What 2 voltages is a short circuit made of?
Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.
Working diag of simple digital security system?
he circuit works off a 9V regulated power supply. However, battery back-up is recommended. A common-cathode, 7-segment display (LTS543) is used for displaying whether the loops are intact or not. If loop 1 is broken, the display will show '1'. If two or all the three loops are broken, the display will show the sum of the respective broken loop nently. The loops are also connected to a dual 3-input NOR gate and inverter CD4000 (IC2) to activate the alarm. Fig. 1 shows the circuit of the digital security system, while Fig. 2 shows the proposed wiring diagram for the loops around the premises. Before using this security system, make sure that loops shown in Fig. 2 are connected as shown in Fig. 1. If you don't want to use a buzzer, switch it off by opening switch S2. The circuit works off a 9V regulated power supply. However, battery back-up is recommended. A common-cathode, 7-segment display (LTS543) is used for displaying whether the loops are intact or not. If loop 1 is broken, the display will show '1'. If two or all the three loops are broken, the display will show the sum of the respective broken loop numbers. For example, if loops 1 and 4 are broken, the display will show 5(1+4). When all the three loops are intact, the display will show '0.' All the three inputs of gate N1 remain low to give a high output. This high output is further given to gate N2 and, as a result, its output remains low. This keeps transistor T1 in cut-off position and the piezobuzzer does not sound. When any loop is broken, the output of NOR gate N1 goes low, while the output of gate N2 goes high. Transistor T1 conducts and the buzzer sounds to alert you. You can mute the buzzer by switching off power to the circuit through switch S1.
What is the differnce between series and parallel circuits?
series uses 1 line of electricity,(1 cable) so if somewhere along the line breaks, the whole series breaks, like light bulbs in a xmas tree.. whereas if you have parallel, its like a mains pipe running water to your house. . your neighbours pipe mite burst but you'll still get water :) ...transfer energy via electrons
Why current gets divided in parallel combination but not in series combination?
Current travels in loops. In series you have one loop, or path for current to take. With parallel connections, there's at least two. This is why current divides in parallel and not in series.
Why kirchhofs is use parallel in circuit?
Note about the spelling: Kirchhoff has a double "f". Basically, Kirhhoff's Laws are valid under a wide variety of situations. Specifically, you can use them in both parallel and series circuits, and in more complicated cases (such as multiple current loops). In the case of parallel circuits:Kirchhoff's Voltage Law tells us that the voltage between the two endpoints is the same, no matter what route is taken.Kirchhoff's Current Law tells us that the sum of the currents in the different branches must be equal to the total current before (or after) the parallel branching.About the question, "why use these laws?" - basically, because they help us figure out the circuit.
What is a ground loop isolator?
Ground loop isolators are used to break the DC circuit path for the audio shield ground circuit. It removes ground loops from the system, which are unwanted.
What type of circuits have loads of separate branches of loops?
parallel circuitsThey could be called twin-loop circuits but it isn't a term in common use.
The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
