Study Notes
Electric Current
- Named after Andre-Marie Ampere, a French physicist who contributed significantly to electricity and magnetism.
- Measured in amperes, represented by the symbol I.
- Represents the flow of electrons through a conductor.
- Measured using an ammeter.
- Common sources include dry cells and batteries, which push electrical charges through the circuit.
Voltage
- Named after Italian physicist Alessandro Volta, inventor of the voltaic pile (now referred to as a dry cell).
- Represented by the symbol V and provides the energy necessary for charges to flow in an electric circuit.
- Measured using a voltmeter.
Resistance
- Refers to the opposition or hindrance to the flow of electric charges in wires and loads within a circuit.
- Represented by the symbol R and measured in ohms (Ω).
- Named after German scientist Georg Simon Ohm, who formulated the fundamental laws of electrical resistance.
