The current waveform in Fig. 6.80 flows through a 3-H inductor. Sketch the voltage across the inductor over the interval 0 6 t 6 6 s.

Electrical Engineering notes: Current, voltage and power: Electric current means flow or movement of charge. A battery connection to a resistor or led using conducting wires Current can flow through conductors such as copper, gold or silver (most conductive). It can also occur in semiconductors DC current means that the current magnitude does not change with time. AC current means that the current magnitude changes with time. Power is found by taking the product of the voltage and the current concerned Materials of relevance in EE can be classified into several broad classes: conductors, semiconductors, magnetic, and dielectric or insulting Examples of each: Conductivity (s/m) – conductivity of copper, resistivi
