Question
Calculate the equivalent resistance of the circuit given below.
- 50 Ω
- 100 Ω
- 300 Ω
- 450 Ω
Hint:
For the resistors connected in series, equivalent resistance can be calculated by the sum of the individual resistance loads. i.e. Req. = R1+R2+R3
The correct answer is: 450 Ω
The equivalent resistance of the circuit is 450Ω.
- The equivalent resistance in the resistors connected in series can be calculated by the formula Req= R1+R2+R3
- The R1, R2, and R3 are 100Ω, 300Ω, and 50Ω respectively.
- So the R= 100+ 300+ 50= 450Ω
