Current Electricity

Direct Current- Current that flows in one direction. Ex. battery devices.

Circuits- A circuit is a closed loop that electrons can travel in. A example of a circuit could be when you turn on a light in your house.

Load- Load is how much electric power is being consumed by something. A light bulb would need 2 to 100 watts of energy.

Switch- Switches are used to turn the flow of electricity on or off. A light switch would be an example of a switch.

Connecting Wires- A connecting wire allows electric current to flow through the wire without resistance. An example of connecting wires could be a battery in a car with the positive, and negative wires.

Voltmeter- A instrument that measures the voltage or potential difference between two points of a electrical circuit. You could check the voltage of a battery with a voltmeter.

Ammeter- An ammeter measure how may amps are going through a circuit. Amps are how much electricity is going through a circuit. You could measure the current of a car.

Resistor- A resistor is an electrical component that limits or regulates the flow of electrical current in a circuit. Some led lights have resistors. A resistor is measured in ohm's.
