Which term describes components that store, dissipate, or filter energy?

• A. Passive Component
• B. Active Component
• C. Signal Source
• D. Load

Answer: (A)

The key idea is how components handle energy in a circuit. Those that store energy in fields (like capacitors and inductors), dissipate energy as heat (like resistors), or shape signals through filtering (also using capacitors and inductors) are called passive components. They don’t generate power or amplify signals; they simply absorb, store, or release energy supplied by other parts of the circuit. Active components, by contrast, can source or amplify power, while a signal source generates a signal and a load is the part that consumes power. So, the term that describes components that store, dissipate, or filter energy is passive component.
