Question

Find the current flowing through 15 ohm resistance using Thevenin theorem​

Answer 1

Answer:

Here we see that:-

3

15

=

4

20

Hence, the wheat-stone bridge is balanced, and no current flows through the galvanometer..

The equivalent circuit is shown:-

Now, the given circuit is in parallel connection of resistance with resistance along ABC =18 ohm and along ADC=24 ohm

Now, i

1

=

24+18

24

×2.1A

⟹i

1

=1.2A

Hence,current through 15 ohm resistor is 1.2A.
