Current Electricity

• Electric current is the steady flow of electrons
  along a wire.
• A circuit is the path the electrons take.

Current Electricity

• The rate of current flow is measured in amperes,
  or amps (A)

5
Current Electricity

• The rate of current flow is measured in amperes,
  or amps (A)
• It tells how many electrons are in the circuit

6
Current Electricity

• The rate of current flow can change according to
  how many electrons are in the circuit, or how
  fast they are going.

Current Electricity

• Electrical Energy is the energy of charged
  particles (electrons)

• Electrical Energy is the energy of charged
  particles (electrons)
• Voltage is used to measure how much electrical
  energy the electrons have.

How we measure Volts and Amps

• A voltmeter measures volts. It is connected
  across a load.

17
How we measure Volts and Amps

• An ammeter measures the current (Amps) in a
  circuit. It is connected in a way that makes all
  the electrons pass through the meter.
