Which component of a radio transmitter provides electrical power?

Explanation:
Providing the electrical power to the transmitter is the job of the power supply. It takes wall power or a battery and converts it into the stable voltages and currents that all the other stages need to function. The oscillator uses that energy to generate the RF carrier at a steady frequency, the modulator uses more energy to imprint the information onto that carrier, and the antenna then radiates the resulting RF energy. Without a power supply delivering the necessary energy, nothing in the chain operates.
