Question

A 10 ohm resistor is connected in parallel across the series combination of 4 ohm and 6 ohm resistors . Calculate the amount of heat produced per second , in 4 ohm resistance if 10J heat is produced per second in 10 ohm resistor

Answer 1

Answer:

4W

Explanation:

R1= 4 ohm

R2=6ohm

R=6+4 ohm

= 10 ohm

P=I²R

10= I²*10

I =√10/10

I=√1

I =1A

P=I²R

=(1)²*4

=1*4

=4W
