Resistor Rules Electricity Lesson 8

Learning Objectives To know and derive the rules for resistors in series and parallel.

Recap What are the circuit rules for current and potential difference?

Potential Difference Rule 1

Resistors in Series The pd across all the components is equal to the sum of the pds across each component:- Using R=V/I, we can write:-

Resistors in Series The resistance across all three resistors is:- Then cancelling the Is on the right hand side:-

Quick Question (a) What is total resistance of the three resistors connected in series?

Resistors in Parallel

The current splits at a junction but the potential difference is the same across both:- Using R=V/I we can say:-

Resistors in Parallel So it follows that:- Dividing throughout by V gives:-

Resistors in Parallel What is the resistance across the two resistors if R 1 = 10 Ω? R 2 = 5 Ω? If it is a 1.5 V cell evaluate I, I 1 and I 2 ?

Practice Calculation What is the resistance across the 4 ohm and 8 ohm resistors? What is the total resistance? What is the current in each part of the circuit?
