Question
Calculate the equivalent resistance of the circuit given below.
- 3 kΩ
- 10 kΩ
- 13 kΩ
- 18 kΩ
Hint:
The total eq. resistance of the circuit for resistors in series, can simply be calculated as the sum of the individual resistance loads.
The correct answer is: 18 kΩ
The total equivalent resistance in the given circuit is 18 kΩ.
- The total resistance in a circuit which has a series of resistors can be calculated as the sum of all the resistances.
- The total resistance in a series Req.= R1+R2+R3
- The resistances produced by R1, R2, and R3 are 3kΩ, 10kΩ, and 5kΩ respectively.
- Hence, R= 3+10+5= 18kΩ is the total equivalent resistance in the given circuit.
