Study Notes
Electric Current
- The movement of electrons through a conductor.
- A cell causes the flow of electrons.
- Electrons always flow from the negative terminal to the positive terminal.
- Conventional current flows from the positive terminal to the negative terminal.
Electric Circuit
- A continuous and closed path of an electric current.
- A circuit where resistors are in parallel 1/Rp=1/R1 + 1/R2 +1/R3.
Components of Electric Circuits
- Electric cell: A device that provides electrical energy.
- Battery: A group of cells connected together to provide a larger voltage.
- Plug key or switch: A device used to open or close the circuit.
- Electric bulb: A device that converts electrical energy into light.
- Resistor: A device that resists the flow of electric current.
- Variable resistance or rheostat: A resistor with adjustable value.
- Ammeter: A device that measures electric current in amperes.
- Voltmeter: A device that measures electric potential difference in volts.
- Wire joint: A connection between two wires.
