Question

the voltage of a circuit is changed from 6 v to 12v resistance remaining the same what will be the current?​

Answer 1

Initially,

• Current = I
• Potential Difference (V) = 6V
• Resistance = R

We know, V = IR

6 = IR..(1)

When potential difference is changed ,

• Potential difference = 12 V
• Current = I'
• Resistance = R

12 = I'R....(2)

Dividing 2 by 1

I'/I = 12/6

I' = 2I

• Current is doubled....
