Activities
- Define a current.
- What unit do scientists measure voltage in? What household objects might you see a voltage measurement on?
- Match the electrical variable to the appropriate unit of measurement.
- Draw a model of a simple electric current.
- There are two main types of currents: alternating current (AC) and direct current (DC). In a DC current electrons flow in one direction. Batteries are an example because the negative side flows to the positive side. An AC current pushes the electrons back and forth, changing the direction of the flow many times per second, generators create an AC.
Conduct some research to answer the following questions about currents:
- Which type of current is more useful?
- How has current technology changed over the years?
Answer Key/Rubric
- Current is the flow of charged particles through a conducting medium, such as a wire.
- Joules per coulomb, or volts

- Acceptable responses might include, but are not limited to:
- Typically AC is used now, because it is able to change voltage amounts. AC currents allow homes to operate at lover voltages, thus being safer.
- Batteries are good DC conductors because they are stored chemical energy, and when in a closed current, create electrical energy. DC is more typical for technologies because although they may be plugged into a wall, the AC current is switched to DC within most devices.
