Question

An electrical motor has a
resistance of 20 ohms. When this
electrical appliance is
connected to a 240 V supply
line, the current passing
through it will be:
a) 1.2 A
b) 12 A
c) 24 A
d) 2.4 A​

Answer 1

Answer:

Option b) 12A is correct

Explanation:

as per given conditions,

R = 20 ohms and V = 240 volts

We know a relation----

V = I R

I = V/R

I = 240/20

I = 12 Amperes
