Question

#An electric iron is rated at 250V, 1500W. Calculate the
maximum current and the number of units it would use in 30 minutes? ​

Answer 1

Explanation:

(a) V = 230V, P = 750 W, t = 30/60 = 0.5hr

(i) Let max current be I

We have P = VI

750 = 230 x I

I = 3.26 A

(ii) Electric energy consumed, E = P x t = 0.75kW x 0.5h = 0.375 kWh

No. of units used in 30 min = 0.375

Answer 2

Answer:

0.75units
