What Gain Value Does a Passive Circuit Have?

💡 The Answer

• A passive circuit will have a gain of less than one.
• Passive circuits cannot add energy; they can only attenuate or filter signals.
• Examples include resistors, capacitors, and inductors without external power.
• Gain less than one means the output signal is weaker than the input.
• This is why passive circuits are not used for amplification.
