Series and Parallel Circuits

Question 1

Current in Series Circuits.

Answer 1

Same throughout every component.

I = I(1)= I(2) =I(3)

Question 2

Current in Series Circuits.

Answer 2

Same throughout every component.

I = I(1)= I(2) =I(3)

Question 3

Current in Parallel Circuits.

Answer 3

-Total current supplied from the battery is shared between each component
-Component with the least resistnace has the largest current flowing through it
I = I(1)+ I(2) =I(3)

Question 4

Voltage (P.D.) in Series Circuit.

Answer 4

-Total voltage across the battery is shared between each component
-Component with the least resistnace has the least voltage across it
I = V(1)+ V(2) =V(3)

Question 5

Current in Parallel Circuits.

Answer 5

-Total current supplied from the battery is shared between each component
-Component with the least resistance has the largest current flowing through it
I = I(1)+ I(2) +I(3)

Question 6

Voltage (P.D.) in Series Circuit.

Answer 6

-The total voltage across the battery is shared between each component
-Component with the least resistance has the least voltage across it
V = V(1)+ V(2) +V(3)

Question 7

Voltage in Series Circuits.

Answer 7

Same throughout every component.

V = V(1)= V(2) =V(3)

Question 8

Resistance in Series Circuits.

Answer 8

R = R(1)+ R(2) +R(3)

Question 9

Resistance in Parallel Circuits.

Answer 9

1/R=1/R1 + 1/R2 + 1/R3

Question 10

Open branch in Series Circuits.

Answer 10

No current flows in the whole circuit.

Question 11

Open branch in Parallel Circuits.

Answer 11

• Current stops flowing in the branch that is open

- Current continues to flow in other branches

Question 12

Discuss the difference between cells in series and cells in parallel.

Answer 12

For cells in series, the total voltage is the sum of the individual voltages.
For cells in parallel, the total voltage is equal to the voltage across one of the cells.
