Question

An.Electric heater os rated 1000 watt,200 volt. Calculate the resistance of the heating element and the current flowing. ....

Answer 1

We know that P = V ^2/R

So... R = V^2/P

So putting the values..

R = 200 × 200/1000 = 40 ohm.

So current will be ...

V = IR

SO..I = V/R

= 200 /40 = 5A

Answer 2

Answer:

We know that P = V ²/R

∴ R = V²/P  

∴ putting the values..  

R = 200 × 200/1000 = 40 Ω.

∴ current will be ..

V = IR

∴I = V/R  

= 200 /40 = 5A
