False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.

How parallel resistors work?
When resistors are connected in parallel in an electrical circuit, they provide multiple pathways for the current to flow. This decreases the total resistance in the circuit, as the equivalent resistance is calculated differently from resistors in series. The total current is divided among the parallel resistors based on their individual resistances.
Does more current flow through a parallel circuit than a series circuit?
In a parallel circuit, the total current is divided among the branches, so each branch may have more current flowing through it compared to a series circuit where the same current flows through each component.
What is a parallel series?
A parallel series circuit is a combination of components where some components are connected in series, and parallel branches are connected in parallel across them. This configuration allows for different pathways for current flow and voltage drop. It is often used in more complex electrical circuits to achieve specific functionality.
When a 30.0-V emf device is placed across two resistors in series a current of 14.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel?
There is insufficient information in the question to answer it. 30 volts generating 14 amperes means the two resistors have a total series resistance of 2.143 ohms. Since no relationship was stated, we don't know the value of the individual resistors. If the two resistors had the same resistance, the net parallel resistance would be 0.536 ohms, and a current of 56 amperes would flow.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
What is the current for two resistors 25 amp and 35 Amp connected in parallel?
"Amp" is not a specification associated with resistors. It could be anything.
How are parallel resistors connected?
If you need a resistor of a certain value, and you have no resistors with small enough values,you can create the one you need by connecting several of those you have in parallel.The effective net resistance of resistors in parallel is always less than the smallest individual.And the more resistors you add in parallel, the smaller the net effective resistance becomes.
A resistor has a resistance of 176 ohm How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220 volt supply line?
4 resistors were connected in parallel it yields 5A of current from 220V supply.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
Does more current flow through a parallel circuit than a series circuit?
In a parallel circuit, the total current is divided among the branches, so each branch may have more current flowing through it compared to a series circuit where the same current flows through each component.
Can two electric resistors connect in both series and parallel?
yes two resistors can connect both in series and parallel because when you connect two resistors in a closed loop, the same intensity of current flows across them and also they are connected to the same nodes which are the conditions for series and parallel connections respectively.
Why a circuit will produce a loading effect?
This happens because the total parallel resistance is lower than the individual resistors that make up the group of parallel resistors. When you add another parallel load, the resistance of that parallel group lowers and as result increases the current for the rest of the circuit.
What quantity varies place to place in a parallel circuit?
In a parallel circuit, the current flowing through each branch varies from place to place because the total current splits up and takes different paths. Voltage remains the same across all branches in a parallel circuit.
What is a parallel series?
A parallel series circuit is a combination of components where some components are connected in series, and parallel branches are connected in parallel across them. This configuration allows for different pathways for current flow and voltage drop. It is often used in more complex electrical circuits to achieve specific functionality.
What is the current in a circuit with 9 volts 3 ohms 2 ohms and 4 ohms?
The current in the circuit will depend on how the three resistors are wired. Series? Parallel? Series parallel? With the resistors in series, 3, 2 and 4 ohms will add to 9 ohms. As I = E/R, I = 9 V / 9 ohms = 1 A. With the resistors in parallel, the 3, 2 and 4 ohm resistors will draw 3 A, 4.5 A and 2.25 A respectively, and the total current will be the sum of the branch currents, or 3 A + 4.5 A + 2.25 A = 9.75 A. There are 3 different series parallel circuits possible, and more investigation will be necessary to solve for them.
What has a larger current the parallel circuit with 1 resistor or the parallel circuit with 2 resistors?
By Ohm's law, current is voltage divided by resistance.In order to determine which circuit draws more current, you need to look at voltage and resistance. Assuming similar voltage, then, less resistance would result in more current.Now you need to know the values of the resistors in both cases. You did not state those important pieces of information. The net resistance of two resistors, R1 and R2, in parallel is R1 time R2 divided by (R1 plus R2). All you need to do is calculate for the two cases.If the two resistors were the same, you can generalize the answer by saying that, with contant voltage, two similar resistors in parallel will pull more current than one similar resistor - specifically, two will pull twice the current of one.
Does parallel wiring make the batteries last twice as long?
No. Parallel wiring just gives the current more choices of where it can flow. What matters is the number of resistors in the circuit.
