Question

5. A heater is rated as 220V, 800W. What is the current drawn by the heater when connected
to a 220V d.c mains?
A. 4A
D. 2.75A
B. 27.5A
E. 8A
C 2A​

Answer 1

Answer:

answer- 2.75A is the correct one

Answer 2

The current is 4 A.

(A) is correct option.

Explanation:

Given that,

Voltage = 220 V

Power = 880 W

We need to calculate the current

Using formula of power

$P=IV$

$I=\dfrac{P}{V}$

Where, P = Power

V = Voltage

Put the value into the formula

$I=\dfrac{880}{220}$

$I=4\ A$

Hence, The current is 4 A.
