"You've got time to work on it and finish!" - Mr. Fitzgerald
- It is generally applied only to direct current (DC) circuits, not alternating current (AC) circuits. In AC circuits, because the current is constantly changing, other factors such as capacitance and inductance must be taken into account.
- The concept behind Ohm's law was first explained by German Physicist Georg Ohm who the law is also named after.
- The tool for measuring volts in an electric circuit is called a voltmeter. An ohmmeter is used for measuring resistance. A multimeter can measure several functions including voltage, current, resistance, and temperature.

An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. The movement of free electrons through the conductors of a circuit is called a current or flow.
