Question

resistance of the electric heater is 200ohms .when 3A current is passing through it what is its power?​

Answer 1

Answer:

when current I is passing through a resistor R, the electric power that generates heat is given by the formula I²R. so,

P= I²R

Here P is power/heat produced,I is current and R is resistance.

P = (2.5)²X 200

= 6.25 x 200

= 1250 Watts.
