Question

two ions p and q have resistance of 10 ohm San 2002 and connected to voltage source of 220 for 3 minutes find the ratio of heat generated in p to q​

Answer 1

Answer:

Heat produced , H=I

2

Rt

here,

=10⇒I

10

=

2

. This is the current through resistor 5Ω.

Voltage across resistor 5Ω is V

5

=I

×5=5

2

V

As resistors (4,6) and 5 are in parallel, so potential across (4,6) is equal to V

5

.

As resistor 4 and 6 are in series so current through each resistor I

4

=I

6

=

4+6

V

5

=

4+6
