Question

a potential difference of 220 volt is applied across a resistance of 440 ohm's is an electric appliance calculate the current drawn and heat energy produced in 20 seconds​

Answer 1

Answer:

current will be 0.5ampere and heat will be 2.2kj

Explanation:

if you need full answer comment to me

Answer 2

Answer:

we know that V=IR

I=V/R

here V=220 ,R=440 Ohm.

so I=0.5 A.

.Heat produced H=VIt

=220*0.5*20

=2200

H=2.2Kj
