1
Q
State Kirchhoff’s Second Law.
A
sum of emfs = sum of voltage
2
Q
State Kirchhoff’s First Law.
A
at any point in an electrical circuit, the sum of currents entering a junction = the sum of currents leaving it
3
Q
Define potential difference.
A
the change in potential energy per unit charge between two points due to the charge doing work on circuit components

A
Rₜ = R₁ + R₂
5
Q
State the rule for total voltage in series circuits.
A
Vₜ = V₁ + V₂
