Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following devices is used to measure electric current in a circuit?
Voltmeter
Ammeter
Ohmmeter
Galvanometer
2. How is a voltmeter connected in a circuit to measure voltage across a component?
In series
In parallel
Either in series or parallel
It doesn't matter
1. Electric current is measured in , while voltage is measured in .
2. An ideal ammeter has a very resistance, and an ideal voltmeter has a very resistance.
1. An ammeter must be connected in parallel with the component whose current is to be measured.
True
False
2. Voltage is also known as potential difference.
True
False
1. Explain the difference between electric current and voltage in a circuit.
2. Describe the characteristics of an ideal ammeter and an ideal voltmeter.
Analyze the circuit diagram below and answer the questions. (Note: Assume ideal meters.)
a) Is the ammeter (A) correctly placed to measure the total current in the circuit?
b) Is the voltmeter (V) correctly placed to measure the voltage across resistor R3?
