Question 1

Series circuit

Answer 1

A circuit where electrical components are connected one after another in a single loop (a circuit that only has one path for the current to flow through)

Question 2

What happens when one component breaks in a series circuit?

Answer 2

The current will not be able to flow round the circuit; if one component breaks, then all of the other components stop working

Question 3

Rule for current in series

Answer 3

The same current passes through each component connected in series

Question 4

Rule for potential difference in series

Answer 4

The total potential difference of the power supply is shared between components connected in series

Question 5

Rule for resistance in series

Answer 5

The total resistance of two components connected in series is the sum of the resistance of each component

Question 6

Parallel circuit

Answer 6

A circuit where electrical components are connected alongside each other on multiple loops; a circuit that has multiple paths for the current to flow through

Question 7

What happens if one component breaks in a parallel circuit?

Answer 7

The current can still flow round the circuit through one of the other paths; if one component breaks, the other components still work

Question 8

Rule for current in parallel

Answer 8

The total current through the whole circuit is the sum of the currents through the separate components

Question 9

Rule for potential difference in parallel

Answer 9

The potential difference across each component is the same

Question 10

Rule for resistance in parallel

Answer 10

The total resistance of two resistors is less than the resistance of the smallest individual resistor

Question 11

I(1) = I(2) = I(3)

Answer 11

The mathematical relationship for the current through components connected in series

Question 12

V(total) = V(1) + V(2)

Answer 12

The mathematical relationship for the total potential difference in a circuit when components are connected in series

Question 13

R(total) = R(1) + R(2)

Answer 13

The mathematical relationship for the total resistance in a circuit when components are connected in series

Question 14

I(total) = I(1) + I(2)

Answer 14

The mathematical relationship for the total current in a circuit when components are connected in parallel

Question 15

V(1) = V(2) = V(3)

Answer 15

The mathematical relationship for the potential difference across components connected in parallel
