Question

the potential difference between the terminals of an electric heater is 40 volt when it draws a current of 5 ampere from the source if the potential difference is increased to 120 volt then the current drawn by heater will be what

Answer 1

Answer:

the current would be 15 A

Explanation:

v-40v

i-5a

v/i=r

then R=8 ohm

now, I=v/r

then hy applying the vaues

we get current to be 15 ampere
