Answer 1

The total resistance in the circuit, R is 4 Ω .

The meters connected to the 12 Ω resistance are:

1. Voltmeter - connected in parallel
2. Ammeter - connected in series

If the switch is opened, only the 4 Ω and 2 Ω resistances will stop working.

What is the equivalent or total resistance in the circuit?

The resistances in the circuit are connected both in series and in parallel

The resistances in series are the 4 Ω and the 2 Ω resistances.

Equivalent resistance = 4 + 2 = 6 Ω

The 4 Ω and the 2 Ω resistances are then connected in parallel with the 12 Ω resistance.

Total resistance, R is calculated as follows:

1/R = 1/12 + 1/6

1/R = 3/12

R = 12/3

R = 4Ω

The meters connected to the 12 Ω resistance are:

1. Voltmeter - connected in parallel
2. Ammeter - connected in series

If the switch is opened, only the 4 Ω and 2 Ω resistances will stop working because the circuit connecting them to the cell is broken whereas the circuit to the 12 Ω resistance is continuous.

In conclusion, resistances can be connected in parallel or in series.
