4.5 + 4.4 Series and parralel

Question 1

What is the relationship between the individual resistance and total resistance in a series circuit

Answer 1

The total resistance in a series circuit is the sum of the individual resistances

Question 2

Describe relationship between the individual resistance and total resistance in a parallel circuit

Answer 2

The total resistance must be lower than the lowest individual resistance

Question 3

Is the current shared throughout a series circuit or does it stay the same?

Answer 3

same

Question 4

How do you work out the potential difference in a series circuit

Answer 4

Sum the potential differences across each individual component

Question 5

What would happen to the current, potential difference and resistance in a series circuit if you added more resistors

Answer 5

• total resistance increases because more resistors are added
• total potential difference is unchanged
• total current decreases

Question 6

What would happen to the current, potential difference and resistance in a parallel circuit if you added more resistors

Answer 6

Decreases total resistance
Potential difference is the same
Current increases
