Question

A lamp of resistance 80 ohm draws a current of 0.75a, find the line voltage

Answer 1

voltage = current × resistance

v =0.75×80=60

Answer 2

Given =》

Resistance = 80 ohm

Current = 0.75 A

To find =》

Line voltage =?

Formula used =》

Voltage = Current × Resistance

V= I R

Solution =》

V= I R

V= 0.75×80

V= 60 volt

So, the line voltage = 60 volt.
