EMF & PD

Voltage is measured in __.

• volts.
• watts.
• coulombs. 

A voltmeter should be placed ........... in a circuit

• in parallel
• in series
• in order
• upside down

What would the voltmeter read

• 1V
• 2V
• 3V
• 6V

Which Voltmeter will give the lowest reading?

• V1
• V2
• V3

Voltage can be measured using ............

• ammeter

• light bulb

• resistor

• voltmeter

• the average force acting on electrons in the battery.

• the total gain in K.E. and P.E. of electrons in the battery.

• the electric potential energy provided to each unit of charge by the battery.

• the speed of electrons after passing through the battery.

What gets moved in electrical systems?

• charge

• frequency

• voltage

• resistance

How are V_S, V₁ and V₂ related to each other?

• V_S = V₁ = V₂

• V_S = V₁ + V₂

• V_S = (V₁ + V₂)/2

• V_S = 2(V₁ + V₂

How are V_S, V₁ and V₂ related to each other?

• V_S = V₁ = V₂

• V_S = V₁ + V₂

• V_S = (V₁ + V₂)/2

• V_S = 2(V₁ + V₂)

If the voltage across the battery was 10V in this diagram. What would the voltage across each bulb be?

• 10V
• 5V
• 20V
• 0V
