Question

What apparatus is used in the maximum power transfer theorem?

Answer 1

In the Maximum Power Transfer Theorem, the primary apparatus used includes:

1. Source of Power (Voltage Source or Current Source): This is the source of electrical energy for the circuit.
   

  

1. Load Resistance (RL): The component to which the power is being delivered. The value of the load resistance is adjusted to find the maximum power transfer.
   

1. Source Resistance (RS): This represents the internal resistance of the power source or the impedance between the source and the load.
   

1. Measurement Instruments (optional but useful): These can include:
   

   - Voltmeter to measure voltage across the load.
   - Ammeter to measure current through the load.
   - Wattmeter to measure the power delivered to the load.

Concept:

The Maximum Power Transfer Theorem states that maximum power is transferred to the load when the load resistance (RL) equals the source resistance (RS).
