Topics in Electricity
Monitoring AC
Alternating current electricity is made by electrical generators.
The current and voltage change over time.
Circuit Theory
Looking at circuit theory. Finding the relationships between potential difference, current and resistance.
Internal Resistance
All electrical sources can be considered a source of emf with an internal resistance.
Capacitors
Capacitors are such an important component in electrical devices. They are used in many timing circuits and can block ac signals.
Semiconductors
Semiconductors and pn junctions are found in all electronic equipment.
