Question

Two heater,one rated 440W at 220V and the other 880W at 220V,are connected in parallel to the electric supply at 220V (i) draw a circuit diagram to show the connection (ii) calculate the current drawn from the electric supply by the heater.

Answer 1

Answer:

this is not the question of Biology disease of Physics

Answer 2

Answer:

Total current drawn = 6 A

Explanation:

Given data;

1st heater rating

power = 440 W

voltage = 220 V

2nd heater rating

power = 880 W

voltage = 220 V

a) circuit is attached below

b) current can be calculated as below

$I_1 = \frac{P}{v} =\frac{440}{220}$

$I_1 = 2 A$

$I_2 = \frac{P}{v} =\frac{880}{220}$

$I_1 = 4 A$

 Total current drawn = 4+ 2 = 6 A
