Question

How does this compare to the usual household voltage if Raman’s air-conditioner consumes 2160 W of power, when a current of 9.0 A passes through it.

Answer 1

we know that,
P =VI
P = 2160W
I = 9A
V = ?
P = VI
2160 = V*9
V = 2160/9
V = 240V

Answer 2

Dear Student,

◆ Answer -

Voltage used by Raman's air conditioner is more than household voltage.

● Explanation -

# Given -

I = 9 A

P = 2160 W

# Solution -

Electric power of Raman's air conditioner is given by formula -

P = VI

V = P/I

Substitute values,

V = 2160/9

V = 240 V

As we know, usual household voltage is 220 V. Therefore voltage used by Raman's air conditioner is more than household voltage.

Thanks dear. Hope this helps you...
