Question

A TV draws a current of 5 A from the 240V supply line. What current will thisTV draw when it is connected to 100V supply line.​

Answer 1

Answer:

2.08 A

Explanation:

Case 1 :

Given :

V = 240 V

I = 5 A

From ohm's law we know :

= > R = V / I

= > R = 240 / 5 Ω

= > R = 48 Ω

Case 2 :

We have :

R = 48 Ω

V = 100 V

We have to find current I :

= > I = V / R

= > I = 100 / 48 A

= > I = 2.08 A

Therefore , required current is 2.08 A
