Active Element:
- The elements that supply energy to the circuit is called active element
- These have an ability to control the flow of charge
- Used for current control and voltage control applications
- Examples: Battery, voltage source, current source, diode
Passive Element:
- The element which receives or absorbs energy and then either converts it into heat (R) or stored it in an electric (C) or magnetic (L) field is called passive element
- Do not need any form of electrical power to operate
- Not able to control the flow of charge
- Used for energy storage, discharge, oscillating, filtering and phase shifting applications
- Examples: Resistor, inductor, capacitor
- Unilateral Element: These elements allow conduction of current in only one direction.
- Example: Diode, transistor, voltage source
- Bilateral Element: These elements allows conduction of current in both directions with same magnitude
- Example: Resistance, inductance, capacitance

Constant voltage source isa)Active and bilateralb)Passive and bilatera...
Constant voltage source is active and unilateral.
Explanation:
A constant voltage source is a device that maintains a constant voltage output regardless of the load connected to it. It is commonly used in electrical circuits to provide a stable voltage supply. A constant voltage source can be classified based on its characteristics.
Active and unilateral:
- An active component is capable of supplying power to the circuit, meaning it can generate and deliver electrical energy.
- A unilateral component allows current to flow in only one direction.
- A constant voltage source is considered active because it can supply power to the circuit by maintaining a constant voltage output.
- It is also unilateral because it allows current to flow in only one direction, from the source to the load.
Passive and bilateral:
- A passive component does not supply power to the circuit and relies on an external power source.
- A bilateral component allows current to flow in both directions.
- A constant voltage source is not passive because it actively supplies power.
- It is not bilateral because it only allows current to flow in one direction.
Therefore, the correct answer is option 'C' - active and unilateral.
