Question

two resistors of 2 ohm and 4 ohm are connected in parrallel to a constant direct current voltage in which case more heat is produced?

Answer 1

Heat Produced is given by
Q = i^2Rt , It is directly proportional to the Resistance of the resistor, if the current is constant for a certain period of time.
As here the current too varies due to parallel connection
2 ohm resistor gets 2i/3 A and 4 ohm resistor gets i/3 A

For 2 ohm:
Q= 8i^2/3 J

For 4 ohm :
Q= 4i^2/3 J


So 2ohm resistor produces more heat

Answer 2

Answer:

Explanation:

Heat Produced is given by

Q = i^2Rt , It is directly proportional to the Resistance of the resistor, if the current is constant for a certain period of time.

As here the current too varies due to parallel connection

2 ohm resistor gets 2i/3 A and 4 ohm resistor gets i/3 A

For 2 ohm:

Q= 8i^2/3 J

For 4 ohm :

Q= 4i^2/3 J

So 2ohm resistor produces more heat
