Question

Calculate the equivalent resistance of the circuit given below.

  1. 50 Ω
  2. 100 Ω
  3. 300 Ω
  4. 450 Ω

hintHint:

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
