The main component in an inverter circuit is the

• A. Diode
• B. Capacitor
• C. Transistor
• D. Inductor

Answer: (C)

Inverters convert DC to AC by rapidly switching current through the load. The device that does this switching is the transistor, which works as the on/off switch controlled by a signal. When the transistor turns on, current flows and builds energy in the load; when it turns off, the current path changes and energy is redirected, creating pulses that, with filtering, become an alternating waveform. Other components like diodes provide protection or paths for current, while capacitors and inductors store energy and shape the output, but they do not perform the essential switching that creates the AC output. That switching role is what makes the transistor the main component.
