Read each question carefully and answer to the best of your ability. For multiple-choice questions, circle the correct option. For fill-in-the-blanks, write your answer on the line provided. For short answer questions, use the lines below the question.
1. Which device is used to measure electric current in a circuit?
Voltmeter
Ammeter
Ohmmeter
Thermometer
2. What is the unit of measurement for voltage?
Amperes
Ohms
Volts
Watts
3. Electric current is the flow of through a conductor.
4. Voltage is also known as difference.
5. An ammeter must be connected in with the component to measure its current.
6. Look at the image below. Describe how you would connect an ammeter and a voltmeter to measure the current through the light bulb and the voltage across it.
7. A voltmeter is connected in parallel across the component you want to measure the voltage of.
True
False
8. Increasing the voltage in a circuit will decrease the current, assuming resistance stays the same.
True
False
