100J heat is generated in a resistance of 4ohm in 1 second.What is the potential difference of the resistor?

shouryaparihar529: H=IsquareRt,100=Isquare×4×1, I=25A ,potential difference; V=IR, 5×4=20. so, difference=25-20=5V. hope it will help you:)

Answer:

The potential difference is given as,

V=IR

=5×4

=20V

Thus, the potential difference across the resistor is 20V.

jangirsomdutt5: I think first u need to find current (I)

Legend42: haa

Legend42: So??

jangirsomdutt5: it is incomplete

Legend42: another user gave the ans na

Legend42: -_-

jangirsomdutt5: ok

Legend42: hmmm

jangirsomdutt5: don't mind just telling

Legend42: I didn't mind anything ;)

>The produced heat is given as,

✒ H=I²Rt

✒ 100=I²×4×1

The potential difference is given as,

V=IR

✒ V=5×4

✒ V=20V

Thus, the potential difference across the resistor is 20V.

Hope it helps you...!!!!
