Question

Q31- a) A tube light draws 0.1 A current
from a 220 V supply. What current will this
tube light draw when it is connected to a 110
V supply? (5)​

Answer 1

Given value:

Current flow through the electric iron, I = 3.4 A;

Voltage supply through the circuit, V = 220 V;

As per the ⏩⏩Ohm's Law:

V = IR

Hence,

R = VIR = 2203.4R = 64.706 Ω

Now,

If voltage connected in the circuit change 110 V then the value of current flow the electric iron is:

V = IR

I = VRI = 11064.706I = 1.699

⏩✔Hence, 1.699 A current flow the electric iron when supply of voltage is 110 V
