Answer 3

Question 4

How is current related in a series circuit?

Answer 4

The current at every point is the same

Question 5

How is potential difference related in a series circuit?

Answer 5

The total potential difference E supplied to the circuit is equal to the sum of individual potential differences across the resistors.

Question 6

How is resistance related in a series circuit?

Answer 6

The effective resistance Re is equal to the sum of the individual resistances

Question 7
