An electric iron has a rating of 750w, 220v calcute

Answer 1

Hey Mate!!

Q) An electric iron has a rating of 750w, 220v calculate the current passing through and the resistance when in use.

A) Given ;

P = 750 W

V = 220 V

P = V× I (So) I = $\frac{P}{V}$

I = $\frac{750}{220}$

I = 3.4 A .

Now, by using Ohm's Law ;

R = $\frac{V}{I}$

R = $\frac{220}{3.4}$

R = 64.7 Ω

∴ I = 3.4 A and R = 64.7 Ω

Hope this helps you!!
