The amount of electricity current that flows through a component depends on...
- Potential difference across component
- Resistance of component
Greater potential difference across a component=greater current through the component
Direct current flows in the same direction. Alternating current constantly changes in direction
Circuit breakers and fuses are safety devices designed to break a circuit if the current becomes too high
Electrical energy can be transformed into other types of energy. The rate of this transformation is the power
Charge (coulomb, C) = Current (amp, A) x Time (second, s)
