## What will happen to resistance if current is doubled?

So the resistance will remain constant if current is doubled through doubling the voltage supply. Similarly resistance will have to be halved if voltage is to remain constant, & so on. The resistance of the circuit should be halved to double the current in the circuit.

**What will be the change in the current if the resistance of a circuit is doubled without changing the voltage?**

Current is inversely proportional to resistance so if resistance become double then the current become one -fourth .

### What happens to the current flowing through a circuit if the resistance in the A circuit increases?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

**What happens to the current and resistance if the voltage in the circuit becomes two times?**

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.

## What happens to the current in the series circuit if the resistance is doubled Mcq?

4. If the resistance total in a series circuit doubles, current will: be doubled.

**What is the effect on current in a circuit if both the voltage and the resistance are doubled if both are halved explain?**

i. Inew = 6 mA (Current is directly proportional to voltage; a halving of the voltage will halve the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current.

### What will happen to the current through a circuit if the resistance is decreased?

But current is also inversely proportional to the resistance; a halving of the resistance will double the current.

**What happens to the current in a DC circuit if the voltage is increased but the resistance remains the same?**

So, an increase in the voltage will increase the current as long as the resistance is held constant. Alternately, if the resistance in a circuit is increased and the voltage does not change, the current will decrease.

## What happens to the current in series circuit?

In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. If one bulb burns out in a series circuit, the entire circuit is broken.
