Question 1

What is an advantage of a parallel circuit?

Answer 1

If one component breaks, current still flows through the others.

Question 2

What impact does a thermistor have on a bulb?

Answer 2

At higher temperatures the bulb glows brighter.

At lower temperatures, the resistance is very high and it is dimmer.

Question 3

What happens in a series circuit in terms of current and voltage?

Answer 3

Current - stays the same everywhere

Voltage - shared between components

Question 4

What happens in a parallel circuit in terms of current and voltage?

Answer 4

Current - shared between branches

Voltage - stays the same everywhere
