#### Question

An electrical appliance has a resistance of 25 Ω. When this electrical appliance is connected to a 230 V supply line, the current passing through it will be:

(a) 0.92 A
(b) 2.9 A
(c) 9.2 A
(d) 92 A

#### Solution

(c) 9.2 A

Resistance = 25 Ω

Voltage = 230 V

Current = Voltage/Resistance

I = V/R

I = 230/25

I = 9.2 A

Thus, if an electrical appliance has a resistance of 25 Ω and when that electrical appliance is connected to a 230 V supply line, the current passing through it will be 9.2 A.

Is there an error in this question or solution?
