AC current also rise and fall in sinusoidal

Edison suggested that households be supplied with direct current. However, it is not advisable to use DC because it is extremely difficult to increase or decrease the power distribution requiremen

Can transistors work with ac? Yes. the exact function depends on how you connect the transistor. in addition, the frequency changes the gain of the transistor. use a power bjt for high voltages. T

A dedicated voltage comparator will generally be faster than an operational amplifier for general use put into operation as a comparator. A dedicated voltage comparator can also contain additional fun
