Question

26. If both the potential difference and the resistance
in a circuit are doubled then,
(A) current remains same
(B) current is doubled
(C) current is halved
(D) current is quadrupled​

Answer 1

Answer:

a

Explanation:

v/R =i

v'=2v

and R'=2R

then i'= v'/R'=i

so there is no change in current

Answer 2

Answer:

If both the potential difference and the resistance in a circuit are doubled then, current remains same.

Explanation:

V - IR

V - potential difference

I - current

And R resistance

So, if both V and R are doubled,

2V = I (2R)

V= IR

So, the current remains the same.

If the potential difference and current through a circuit are doubled, then the resistance of the circuit remains the same.
