Question

keeping the potential difference constant ,the resistance of a circuit is double. by what factor does the current change in the circuit?

Answer 1

the current in the circuit become half.

Answer 2

Answer:

The Ohm's law gives the relationship between the potential difference, current and the resistance of the circuit. Mathematically, it is given by :

V = potential difference

I = current

R = resistance

If the resistance of the circuit is doubled, R' = 2R

So, the current will becomes the half of the initial current. Hence, this is the required solution
