In the circuit shown below, calculate the net resistance of the circuit.
Here, the resistances 10Ω and 15Ω are connected in series and also the resistances 20Ω and 5Ω are also connected in series.
Thus, R1 = 10Ω + 15Ω = 25Ω
R2 = 20Ω + 5Ω = 25Ω
Now, these two resistances R1 and R2 are connected in parallel
Thus the net resistance is 12.5Ω.
