Resistors in Series and Parallel

Kitronik Ltd – How to calculate resistors in series and parallel Resistors in series When resistors are connected one after each other this is called connecting in series. This is shown below.

R1

R2

R3

To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is gives the following formula:

Rtotal = R1 + R 2 + R3 and so on Example: To calculate the total resistance for these three resistors in series

100Ω

82Ω

Rtotal = R1 + R 2 + R3 = 100 Ω + 82 Ω + 1 Ω = 183 Ω

Task 1: Calculate the total resistance of the following resistor in series 1000Ω

470Ω

22 Ω

Rtotal = ………………... = ………………...

27Ω

2200Ω

15 Ω

Rtotal = ………………... = ………………...

3300Ω

1500Ω

47 Ω

Rtotal = ………………... = ………………...
