Answer 1

Step-by-step explanation:

Resistance:

The measurement of the opposition of the flow of electric current through a conductor is called resistance of that conductor. It is denoted by R.

There are mainly two ways of the combination of resistances:

1. Resistances in series:

F1 J.K 25.3.20 pallavi D3

When two or more resistances are connected one after another such that the same current flows through them are called resistances in series.

The net resistance/equivalent resistance (R) of resistances in series is given by:

Equivalent resistance, R = R1 + R2

2. Resistances in parallel:

F1 J.K 25.3.20 pallavi D4

When the terminals of two or more resistances are connected at the same two points and the potential difference across them is equal is called resistances in parallel.

The net resistance/equivalent resistance(R) of resistances in parallel is given by:

Calculation:

Reciprocal of resistance is conductance, we convert the conductances into resistances and the circuit will look like this

Given: R1 = 1 Ω , R2 = 1 / 3 Ω , R3 = 1 / 2 Ω

Taking eqivalent resistance of R1 and R2
