Question

derive laws of resistance in series so as to explain equivalent residence of circuit​

Answer 1

Explanation:

electric current flowing through the circuit

V = the potential difference supplied by the battery

Applying the Ohm’s law to the entire circuit, we have

V=IR

On applying Ohm’s law to the three resistors separately, we further have

V

1

=IR

V

2

=IR

and V

3

=IR

3

The total potential difference across a combination of resistors in series is equal to the sum of potential difference across the individual resistors. That is,

V=V

1

+V

2

+V

Therefore, IR=IR

+IR

2

+IR

or

Equivalent resistance of the combination, R=R
