Question

Three identical resistances each of 3 ohm are connected in series and such 3 combination are connected in parallel. Than net resistance will be​

Answer 1

Answer:

If the resistances are in series then total resistance in the circuit is (3+3+3)+1=10 ohm.

So the current in the circuit is I

s

=

10

V

A. Where, V is the battery voltage.

Again, if the resistances are in parallel then total resistance in the circuit is (3∣∣3∣∣3)+1=2 ohm.

So the current in the circuit is I

p

=

2

V

A. Where, V is the battery voltage. So,

I

p
