What happens to the resistance of a circuit if current is doubled?

Answer: If you are doubling the current, either you are doing if by increasing the voltage or by decreasing the resistance or by a combination of both. so the resistance will remain constant if current is boubled through doubling the voltage supply.

How does the current in a circuit change if the resistance is doubled the current is halved?

The current is directly proportional to the voltage and inversely proportional to the resistance. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value.

What will happen if the current is doubled?

Explanation: If current is I and voltage is V , then resistance R=VI and power is given by P=V⋅I . As such when both the current and voltage in a circuit are doubled, resistance becomes R=2V2I=VI and hence remains same. −4V⋅I i.e. power becomes four times.

What would be the value of resistance if voltage is doubled?

20. What happens to current and resistance if the voltage doubles? Current doubles and resistance doubles. Current doubles and resistance is halved.

When the resistance of a circuit is increased the current flowing in the circuit will?

But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current. These two factors offset each other and there is no overall change in the current.)

How will you increase the resistance in a circuit?

Ohm’s Law and resistance length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance.

What happens to the current in a series circuit if the resistance is to?

Ohm’s law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed.

In which circuit the total resistance is greater than the largest resistance in the circuit?

series circuits
Explanation: In series circuits, the total resistance is the sum of all the resistance in the circuit, hence the total is greater than the largest resistance.
