New cards

Potential difference definition

potential difference is the energy transferred per charge carrier from electrical energy to other forms of energy

2
New cards

Potential difference Equation

V = W/Q

∴ V = JC⁻¹

3
New cards

EMF definition

The energy transferred per charge carrier from chemical (or other) energy to electrical energy

4
New cards

EMF equation

E = W/Q

∴ E = JC⁻¹

5
New cards

Difference between emf and p.d in terms of charges

p.d is the work done by the charge carriers

emf is the work done on the charge carriers

6
New cards

Kirchhoff’s Second Law

In any circuit, the sum of the electromotive forces is equal to the sum of the p.d.s around a closed loop

7
New cards

Potential Difference in Series

The sum of the p.d.s is equal to the emf

V = V1 + V2 + …

8
New cards

Potential Difference in parallel

The p.d in each branch is equal to the emf from the power supply

V = V1 = V2 = …
