10.2 Combining Resistors

Question 1

Give the p.d. Rule for 2 or more components in series

Answer 1

The total p.d. = the sum of the p.d. across each component

Question 2

How must comments be arranged to have the same p.d. across them

Answer 2

In parallel

Question 3

Equation for calculating the total resistance for resistors connected in series

Answer 3

R = R1 + R2 + …

Question 4

How is the emf split between resistors when the are connected in series

Answer 4

Split between them in proportion to their resistances

Question 5

Equation for calculating total resistance for resistors connected in parallel

Answer 5

1/R = 1/R1 + 1/R2 + …..
