Question

An 1,840 W toaster, a 1,380 W electric frying pan, and a 70 W lamp are plugged into the same outlet in a 15 A, 120 V circuit. (The three devices are in parallel when plugged into the same socket.) (a) What current (in A) is drawn by each device?

Answer 1

Answer with Explanation:

We are given that

Power of toaster=$P_1=1840 W$

Power of electric frying pan=$P_2=1380 W$

Power of lamp=$P_3=70 W$

Current in circuit=15 A

Potential difference= V=120 V

We know that

Current=$\frac{P}{V}$

Using the formula

Current drawn by toaster=$I_1=\frac{1840}{120}=15.3 A$

Current drawn by electric frying pan=$I_2=\frac{1380}{120}=11.5 A$

Current drawn by lamp=$I_3=\frac{70}{120}=0.58 A$
