1. In which of the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery
Answer:
CIRCUIT 2
Explanation:
IT IS BECAUSE ITS RESISTANCE IS HIGH COMPARED TO OTHER CIRCUITS
HIGHER THE RESISTANCE HIGHER IS THE HEAT PRODUCED
Answer:
Circuit 3
Explanation:
Circuit 3
Because the heat produced i.e., electric current produced will be more.
1) In 1st diagram,
V=IR
I=V/R
Putting the values,
I=12/2
=6A
2) In 2nd diagram,
Req=2+2
=4Ω
I=V/R
=12/4
=3A
3) In 3rd diagram,
1/Req=1/2+1/2
1/Req=2/2
Req=1Ω
So, I=V/R
=12/1
=12A
So, the heat produced will be maximum in the third Circuit diagram because higher the electric current will flow, the more heat energy is produced.
I hope that it will help you!
