You need to know how to investigate how current changes with voltage for a component, eg for a resistor (or wire) at constant temperature, a filament lamp and a diode. You should be familiar with the ...

Electricity can flow either as direct current (d.c.), or alternating current, (a.c.), and is used in homes to power electrical appliances. Direct current (d.c.) Direct current only flows in one ...

This report focuses on DC to AC power inverters, which aim to efficiently transform a DC power source to a high voltage AC source, similar to power that would be available at an electrical wall outlet ...
