Question

A 1,760 W toaster, a 1,420 W electric frying pan, and an 85 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

Toaster = I = 14.67 A

Frying Pan = 11.83 A

Lamp = 0.71 A

Step-by-step explanation:

The electric power is given as:

`P = VI\\\\I = (P)/(V)`

where,

I = current

P = Power

V = Voltage = 120 V

FOR TOASTER:

P = 1760 W

Therefore,

`I = (1760\ W)/(120\ V)`

I = 14.67 A

FOR FRYING PAN:

P = 1420 W

Therefore,

`I = (1420\ W)/(120\ V)`

I = 11.83 A

FOR LAMP:

P = 85 W

Therefore,

`I = (85\ W)/(120\ V)`

I = 0.71 A
