Question

An electrical appliance has a resistance of 40 Ω. When this electrical appliance is connected to a 220 V supply line, the current passing through it will be: a) 6.5 A b) 5.5 A c) 8000A d) 0.18A

Answer 1

b) 5.5 A

Step-by-step explanation:

Use Ohm's Law to solve for I:

I=V/R

V is voltage and R is resistance

V=220V

R= 40 Ω

I=220V/40Ω

I= 5.5 Amps
