Question

If the voltage V in an electric circuit is held​ constant, the current I is inversely proportional to the resistance R. If the current is 60

amperes when the resistance is  255

​ohms, find the current when the resistance is 150

ohms.

Answer 1

I 2 = 900amperes

Explanation:

V = IR

Since v is constant

I1R1 = I2R2

I 2 = I1 x R1 / R2

= 600 x 225 / 150

= 135000/150

= 900 amperes
