Multiple Choice

How do you measure the potential difference?

• scale

• meter stick

• ammeter

• voltmeter

• potentiometer

Multiple Choice

How do you place a voltmeter in a circuit?

• parallel to the component

• in series with the component

Multiple Choice

What did that slide mean?

• current is the same across each component in series

• voltage is the same across each component in series

• resistance is the same across each component in series

Multiple Choice

The sum of the ______ across each component equals the EMF.

• Current

• Voltage drop

• Resistance

Multiple Choice

Calculate the effective resistance of three resistors in series if they have the following values: 1.2 kΩ, 5.6 kΩ and 7.1 kΩ.

• $6800\ \Omega$
  

• $12700\ \Omega$

• $13900\ \Omega$

Multiple Choice

What did that slide mean?

• current is the same across each component in parallel

• voltage is the same across each component in parallel

• resistance is the same across each component in parallel

Current splits to find the easiest path.

Voltage is the same across each component.

Multiple Choice
