We are given the following information.
Resistor: R₁ = 50 Ω
Resistor: R₂ = 100 Ω
We are asked to find the equivalent resistance of this circuit.
Notice that the resistors R₁ and R₂ are in series.
So, their equivalent resistance will be the sum of the individual resistors.
Therefore, the equivalent resistance of this circuit is 150 Ω.
