In the circuit diagram given below five resistances of 10 Ω, 40 Ω, 30 Ω, 20 Ω and 60 Ω are connected as shown to a 12 V battery.
(a) total resistance in the circuit.
(b) total current flowing in the circuit.
(a) when three resistors are connected in parallel, the net resistance can be obtained as followed
The resistance of 30 ohm, 20 ohm and 60 ohm are connected in parallel. therefore, the net resistance R will be
The resistance of 10 ohm and 60 ohm are connected in parallel. Therefore, the net resistance R will be
Now R1 and R2 are connected in series
So total resistance in the circuit is R = 10+8 =18 ohm
(b) Total current flowing in the circuit
