Alternating Current Waveform
The AC current forms a wave similar to the sinusoidal wave, the wave starts from zero and reaches its maximum value then started decreasing to reach the zero value it continues to decrease till it reaches its minimum value(negative maximum value) and then it increases again to reach the zero value. The AC waveform is positive in the first half and negative in the second half.
Alternating Current
Alternating Current and Direct Current are the two types of electricity based on the direction of the voltage and current. In households, we use mostly Alternating Current as the grids are designed to provide alternating current only. But in the case of power storage, DC is used. Alternating currents vary with time so does their voltage.
All the appliances in a common household are wired to work with these types of currents and voltage sources. To understand the workings of these devices in real life, it becomes essential to understand the concepts behind alternating current (AC). Let’s look at these concepts in detail.
