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

Is the voltage dropped across a resistor a waste of energy? Yes and no. the energy is converted into heat and emitted as ir radiation. However, if you want heat, such as in a heater or toaster, then i

Methods of electricity generation There are seven basic methods to convert other forms of energy directly into electrical energy: Static electricity through physical separation and charge transp
