# Ohm's Law quiz

Take this Ohm's law quiz to see how well you understand Ohm's law. After completing this quiz with 100% accuracy, you will know exactly what the Ohm's law is and how to use it to solve problems. You will not need to use a paper and pencil to complete this quiz.

First, read the lesson about Ohm's law and then take this quiz.

Objective of the Ohm's law quiz:

• Identify the Ohm's law formula
• Know what a voltage source is
• Know what an electric resistance is
• Use Ohm's law to find the current or the voltage
 Test your knowledge with the quiz below: 1. Choose the correct equation for Ohm's law I = R/V R = VI I = V/R O = RI. 2. An example of a device that is not a voltage source is Battery Generator Voltage relays Electrical outlets. 3. By analogy, a voltage source is like a water pump an air pump a heart All the above 4. The voltage of a AAA battery is likely to be 20 volts 2 volts 8 volts None of the above 5. The job of an electric resistance is to increase the voltage by resisting the current decrease the voltage by resisting the current decrease the current by resisting the voltage None of the above 6. In which material you will expect the current to flow more easily? 1.5 mm thick and 10 m long 1.6 mm thick and 9.1 m long 1.45 mm thick and 9 m long 1.60 mm thick and 9 m long 7. The positive terminal of a voltage source will attract electrons because electrons have negative charges. electrons have positive charges electrons have positive affinity with the voltage source electrons have negative affinity with the voltage source 8. What is the current of a circuit flowing through a 50 Ohms resistor and powered by a voltage source of 100 volts? 2 volts 1 A 2 A Not enough information 9. If the current flowing through a 6 Ohms resistor is 2 A, what is voltage of the circuit? 24 volts 8 volts 3 volts 12 volts 10. An example of DC is a car battery home outlet car alternator direct current Score = I strongly recommend you try your very best to complete this Ohm's law quiz on your own. Resist the urge to see the answers. Review the lesson about Ohm's law again. However, if you still cannot get 100% on your own, click here to see the answers.
