Question

when a circuit is set up correctly, it is found that a voltage of 3 v gives a current of 0.5a. what voltage would be needed to give a current of 1A?

Answer 1

Answer:

6v

Explanation:

it is found that a voltage of 3 v gives a current of 0.5a. here resistance r is r = v/I = 3/.5 = 6ohm

now the required voltage to get 1 A, v = Ir=1×6 =6v.
