Voltage and Current in Series
• Voltage is shared and current is constant
1 of 7
Voltage and Current in Parallel
• Current is shared and voltage is constant
2 of 7
Kirchhoff’s Second Law
• The sum of the e.m.f round a loop is equal to the sum of the p.d round the same loop
3 of 7
Kirchhoff’s Second Law
E emf = E P.d
4 of 7
Kirchhoff’s Second Law
• This is a consequence of the conservation of energy; since energy cannot be created or destroyed, it must be used in the circuit
5 of 7
Internal Resistance
• All sources of e.m.f have internal resistance
6 of 7
Internal Resistance
• In a battery, this is due to the chemicals inside of it, in a power supply it is due to the components and wires inside
