Physics 2.2.3

Question 1

What is the Difference in terms of Current in Series & Parallel Circuits? (2)

Answer 1

-In a Series Circuit, the Current is the Same at all Points.

-In a Parallel Circuit, the Current Splits at Junctions.

Question 2

What is the Difference in terms of Potential Difference in Series & Parallel Circuits? (2)

Answer 2

-In a Series Circuit, the Voltage of the Power Supply is Shared between the Components.

-In a Parallel Circuit, the Voltage across each Component is the Same.

Question 3

In a Series Circuit, what is the Total Resistance?

Answer 3

The Sum of the Resistance in each Component.

Question 4

2 Resistors in Series will have a ___ overall Resistance than just one. Why is this?

Answer 4

Larger. Because the Charge has to push through multiple Components when Flowing around the Circuit. The more Components the Charge has to travel through, the Higher the number of Collisions that Occur, which Increases Resistance.

Question 5

In a Parallel Circuit, the Total Resistance ___ and is ___ than the Resistance of any of the Individual Components.

Answer 5

Decreases, Less.

Question 6

2 Resistors in Parallel will have a ___ overall Resistance than just one. Why is this?

Answer 6

Smaller. Because the Charge has more than one Pathway to take, so only some Charge will Flow along each path. The more Pathways there are, the Smaller the amount of Charge in each Path. This means less Resistance.
