Voltage the same in parallel circuits?

Question

In a series circuit, current is the same throughout and voltage varies. In a parallel circuit, vice versa. If circuit elements cause voltage drops in a series circuit, won't they cause them in a parallel circuits too? That would make the parallel circuit have different voltages throughout.

Answer 1

Some good answers have already been given.



Here's another point of view.



All the electrical aplliances and lights in your house are wired in parallel across the supply.



The voltage at every connection point (the sockets/outlets) is the same.



Each socket provides a current path, or perhaps several if you have more than one item plugged into it, all of which are in parallel.



The current taken from each socket will depend on what you have connected to it.

Answer 2

No, the parallel circuit presents a single combined resistance, according to the formula: 1/R total = 1/R1 + 1/R2 + 1/R3 ... The same voltage appears across each resistor, but the currents through each resistor may vary. These currents can be added together to give 'I', used in the well known formula: V = I X R.

Answer 3

The Definition of a Parallel Circuit is that all the Elements have the same voltage

Answer 4

to apply a hydraulic analogy, voltage is like the stress of water in a pipe, and contemporary is like the bypass of water in pipes. In hydraulics, stress is a similar everywhere till something motives it to drop. That something is resistance to bypass that could want to be by using an obstruction interior the pipe, or a pipe that's purely too small for the needed bypass price. same element with electrical energy. The voltage utilized to parallel branches in a circuit is a similar-the in elementary words element that could cut back it is electrical powered resistance with a contemporary flowing with the help of the resistance. all of us comprehend that each and each and every one conductors have a small resistance, yet when we draw a circuit diagram we assume that the conductors have 0 resistance and draw resistors the position we've certain lots. So the circuit diagram is idealized to shop issues elementary. in case you actual built the circuit and made careful measurements, you would possibly want to come upon a moderate drop in voltage as you bypass further from the voltage source, yet that could want to oftentimes be small - fractions of a volt - compared to the voltage drop for the period of lots.

Answer 5

Voltage does not vary across ideal wires. Since in a parallel circuit the ends of the elements are wired together, they must all be at the same potential.

Answer 6

A parallel circuit means that you have connected many loads to the same point. How can the same point have different voltages. The voltage between the same points will be the same for all the loads connected to it.If the voltage drops down others connected to the same point will have reduced voltage.

Answer 7

Think of your circuit as pipes with water flowing through them. The pressure is your voltage and the current is the speed which the water flows through that pipe. The resistance would be the size of your pipe.



In a parallel circuit, the pressure on each pipe would be the same, but the water would flow through each pipe at a different rate based on their size.

Answer 8

It kinda hard to under stand what you are asking, but what I know about parallel, is the only time you will see a change in voltage in the circuit is if their is a comparable amount of resistance on the wire. Example take 4 car battery's only with 11.4 volts one with 14.2, another with 12 and 13 volts and wired them all in parallel with speaker wire (about 20 gage) and checked the voltage on each you would see that they don't all read the average of the 4 but if you used 6 gage ( about 1/8 inch real heavy duty) it would average out ohms law... And just a reminder in series you only get as much power (amps) as your weakest link example cover up 1/4 of a solar panel ( multi cell) you lose half of your power. Hope this helps

Answer 9

no. all their terminals are wired together so how could they have differing voltages?

well ok . that's in theory . In real life the wires have some resistance so there is a difference but in almost all real circuits ( except at very high currents) the difference is tiny. like millivolts or even microvolts difference.
