Question

A current of 150 mA (10 raise to -3 ampere) flows through wire when the potential diffrence between its ends is 300 volts find the resistance of the wire​

Answer 1

Answer:

V=IR

R =V/I = 300 ÷ 150 × 10^-3

2 × 10^3

Answer 2

According to Ohm's Law,

The relation between Resistance, volt and current is given as :

V = I×R

Here, V = 300v

I = 150 mA = 150 × 10^(-3)

Hence, R = V/I

=> R = 300/ 150 × 10^(-3)

=> R = (300 × 1000)/150

=> R = 2 × 10^3 ohm

Hope this helps !
