series circuits

Question 1

which components are always connected in parallel?

Answer 1

voltmeter

Question 2

series circuit

Answer 2

a circuit where the different components are connected in a line, end to end between the +ve and -ve of the power supply

Question 3

what happens if one component is removed or disconnected in a series circuit?

Answer 3

the circuit is broken

Question 4

cell potential difference in a series circuit

Answer 4

increases when more cells are connected in series-the pd adds up

Question 5

total potential difference in a series circuit

Answer 5

total pd of the supply is shared between the various components V=V₁ + V₂

Question 6

current in a series circuit

Answer 6

the same current flows through all components I₁=I₂

Question 7

resistance in a series circuit

Answer 7

resistance adds up- the total resistance of two components is R=R₁ + R₂

Question 8

why does resistance add up?-series

Answer 8

by adding a resistor, the two resistors have to share the total pd

Question 9

why is current reduced with more resistors?-series

Answer 9

pd across each resistor is lower so the current through each resistor is also lower, current is the same everywhere so the total current is reduced and resistance increases

Question 10

a bigger resistance

Answer 10

a bigger share of total pd
