Unit 11 · ElectricityCombination of Resistors
Words of This Topic
- Resistor: a part of a circuit that opposes the flow of current.
- Resistance: how strongly a conductor opposes current, measured in ohms (Ω).
- Series combination: resistors joined one after another, giving the current a single path.
- Parallel combination: each resistor connected across the source on its own path.
- Total resistance: the resistance of one resistor that could replace the whole group.
- Reciprocal: 1 divided by a number.
- Ammeter: an instrument that measures current, connected in series.
- Voltmeter: an instrument that measures potential difference, connected across the two ends of a resistor.
