Correct option is D
For a DC circuit, the Maximum Power Transfer Theorem states that:Maximum power is transferred from the source to the load when the load resistance is equal to the internal resistance of the source.Thus,RL=R
A load resistance R_L is supplied from a dc voltage source of resistance R. Maximum power transfer to the load occurs when which of the following condition is satisfied?
Which of the following colour has wavelength between green and orange?
A load resistance R_L is supplied from a dc voltage source of resistance R. Maximum power transfer to the load occurs when which of the following condition is satisfied?
Voltage and current in a single- phase ac circuit are given by (50+j20) V and (20+j50) A respectively. What is the active power consumed in the circuit?
