Key terms in this lesson
- Resistance
- The ratio of the potential difference across a component to the current flowing through it, measured in ohms.
- Internal resistance
- The resistance within a source of e.m.f., such as a cell, which causes a loss of potential difference, or lost volts, when current flows through it.
