Question

1200 W, 2000 W, and 720 W devices will be operated on 220 V at the same time. Calculate the current through each device.

Answer 1

I₁ = 5.45 A

I₂ = 9.1 A

I₃ = 3.27 A

Step-by-step explanation:

Electrical power is defined as the product of current and displacement.

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

where,

P = Power of Device

I = current passing through the device

V = voltage across the device = 220 V

FOR P₁ = 1200 W

`I_1 = (1200\ W)/(220\ V)`

I₁ = 5.45 A

FOR P₂ = 2000 W

`I_2 = (2000\ W)/(220\ V)`

I₂ = 9.1 A

FOR P₃ = 720 W

`I_1 = (720\ W)/(220\ V)`

I₃ = 3.27 A
