The total resistance of the circuit is determined as 450 Ω. (Option D).
How to calculate the total resistance of the circuit?
The total resistance of the circuit is calculated by applying the following formula as shown below.
Rt = R₁ + R₂ + R₃
where;
- R₁ is the value of resistance 1
- R₂ is the value of resistance 2
- R₃ is the value of resistance 3
The given parameters include;
R₁ = 100 Ω
R₂ = 300 Ω
R₃ = 50 Ω
Rt = R₁ + R₂ + R₃
Rt = 100 Ω + 300 Ω + 50 Ω
Rt = 450 Ω
