Electricity

Question 1

The current is the same throughout the circuit, series or parallel?

Answer 1

> series

Question 2

The P.D is shared across the appliances, series or parallel?

Answer 2

> series

Question 3

The potential difference across each component is the same, series or parallel?

Answer 3

Parallel

Question 4

What happens as the resistance of a circuit increases?

Answer 4

The current decreases

Question 5

The current is different in different branches of the circuit, series or parallel?

Answer 5

Parallel

Question 6

For a series circuit, what is the total resistance?

Answer 6

> the sum of all the individual resistors or components

Question 7

Why does increased temperature increase resistance?

Answer 7

> free electrons flow

> as metal gets hotter, ions gain more energy and vibrate more quickly

> electrons collide with the ions more frequently, lowering current that can flow.

Question 8

What is the

> frequency

> voltage

Of mains electricity

Answer 8

> 50Hz

> 230V
