CIRCUITS
1
, Definitions:
Potential Difference: Work done per unit positive charge.
Current: The rate of flow of charge.
Ohms law: Current through a conductor is directly proportional to the potential
difference across the conductor at constant temperature.
Resistance: a materials opposition to the flow of charge/electric current.
Emf: the total energy supply per coulomb of charge by the Cell.
Conventional Current: The flow of positive Charge.
Power: Rate of doing work. / The rate of energy conversion.
