Question

if two identical heaters inch rated 2000 watt 220 volt are connected in parallel to 200 volt then the total power consumed is ___​

Answer 1

Answer:

Explanation:first we have to find equivalent resistance

I.e, R=V/W

=220÷2000 =24.2ohm

Req-R/2 24.2÷2=12.1ohm

Pcombined P=V^2/R

220×220/12.1 =4000 W
