6.2.2 Series and parallel circuits

Question 1

There are two ways of joining electrical components. What are the two ways?

Answer 1

In series and in parallel. Some circuits include both series and parallel parts.

Question 2

For components connected in series:
(current)

Answer 2

there is the same current through each component

Question 3

For components connected in series:
(p.d)

Answer 3

the total potential difference of the power supply is shared
between the components

Question 4

For components connected in series:
(resistance)

Answer 4

the total resistance of two components is the sum of the resistance of each component.

Question 5

resistance in ohms

Answer 5

Rtotal = R1 + R2

Question 6

For components connected in parallel:
(p.d)

Answer 6

the potential difference across each component is the same

Question 7

For components connected in parallel:
(current)

Answer 7

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

Question 8

For components connected in parallel:
(resistance)

Answer 8

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