Voltage and Energy

Question 1

What is voltage?

Answer 1

The energy transferred per unit charge passing between 2 points

Question 2

What is voltage measured in?

Answer 2

Volts (V)

Question 3

How do you measure voltage?

Answer 3

By a voltmeter in parallel with the component being measured

Question 4

What is the formula for voltage?

Answer 4

Energy transferred = Charge X Voltage

Question 5

What is voltage like in a series circuit?

Answer 5

It is shared among components

Question 6

How would 2 components with the same amount of resistance share the amount voltage?

Answer 6

They will be shared equally, equal to half of the total voltage of the power supply

Question 7

How would 2 components with differing values of resistance share the amount of voltage?

Answer 7

They will not be shared equally
-The voltage will be higher across the component with higher resistance

-The voltage will be lower across the component with lower resistance

Question 8

What is voltage like in a parallel circuit?

Answer 8

The total voltage across each branch is the same as the voltage of the power supply
