Do passive circuit components need an external power source?
Active Components and Passive Components To align with the international distinction between active and passive components, mainland China typically refers to them as active devices and passive devices. Active Devices Active devices correspond to active components. Electronic components such as transistors, thyristors, and integrated circuits require an excitation power source in addition to an input signal to function normally, hence the term “active devices.” Active components also consume electrical energy, and high-power active components typically require heat sinks. Passive components Passive components, which encompass both passive electronic components and passive circuit components, are inherently defined by their functional characteristics in electrical systems. Resistors, capacitors, and inductors, as classic examples of these elements, can perform their specified functions in a circuit with the passage of a signal without relying on an external power source—this independence from auxiliary energy is precisely what categorizes them under the umbrella of passive components. Whether viewed as foundational passive electronic components that form the building blocks of device design or as critical passive circuit components that dictate circuit behavior, these elements exhibit a unique energy profile: they consume minimal electrical energy or efficiently convert it into other forms such as heat, light, or magnetic energy, thereby shaping the fundamental operation of electronic systems without active energy amplification.
No, passive circuit components do not need an external power source. They can perform their specified functions in a circuit with the passage of a signal alone, relying on the signal itself rather than auxiliary energy from an external power source. This independence from external power is a key characteristic that defines them as passive components.

What are passive circuit elements and why are they called passive?
Passive circuit elements are components that do not require an external power source to operate and cannot generate energy. They include resistors, capacitors, and inductors, which can only store or dissipate energy. They are termed "passive" because they do not amplify signal power or control the flow of energy—rather, they respond to the energy supplied by active components, such as transistors or operational amplifiers.
Examples of active and passive elements?
active element means that does not work itself it require external power source for working ie electricity or other and passive element means that work ifself does not equire external power source for working ie electricity or other eg. active- compressor need electricity, also tv,computer etc passive- thermometer sens temperature itself (mercury thermometer)
What is driven RL circuit?
A driven RL circuit is a circuit that contains a resistor (R) and an inductor (L) connected in series with an external source of alternating current (AC) or voltage. The external source provides energy to the circuit, driving the current through the inductor and resistor. This circuit can exhibit interesting behavior such as resonance and phase shifts due to the interplay between the inductive and resistive components.
Part of a circuit that does work?
Three basic parts of a circuit are: 1. Active components = source of energy 2. Transmission Lines = wiring and control devices 3. Passive components = load or user of energy
What kind of prosthesis needs no external power source?
Passive prostheses are designed to operate without the need for an external power source. These prostheses are typically made of durable materials and rely on the user's residual limb for support and movement. They do not have any electronic components and are more straightforward in design compared to active prostheses.
What is external circuit?
An external circuit refers to the pathway outside a power source, such as a battery or generator, through which electric current flows to perform work. It typically includes components like resistors, capacitors, and switches that control the flow of electricity. The external circuit connects to the terminals of the power source, allowing energy to be delivered to devices like lights or motors. In essence, it is the complete loop that facilitates the transfer of electrical energy from the source to the load.
What are active and passive transducers?
An example of a passive transducer is differential transformers. The reason why is because passive transducers require an external power supply to operate.
What is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.

Passive prosthetics came about to meet what need?
the need for devices to function without an external power source
What are the differences between a parallel circuit and a series circuit?
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
What are the component of electronics?
Electronic have two type of components Active components and Passive components. Active components are those which increase the power of a signal and must be supplied with the signal and a source of power. Passive components do not increase the power of a signal. Active components are Bipolar transistor, Operational amplifier, field effect transistors etc and Passive components are semiconductor, resistor, capacitor, inductor etc
