Question

An electric iron draws a current of 4 A when connected to a 220 volt mains. Its resistance

must be:

a) 1000 ohm

b) 55 ohm

c) 44 ohm

d) None of these​

Answer 1

Answer:

Given - Current (I) = 4A

Potential Difference (V) = 220V

To find - Resistance (R) = ?

Formula - V = IR

Solution - We know that ,

V = I R

:. 220 = 4 R

:. 220 = R

4

:. R = 55 ohms
