Load Resistance in Output Stages and Power Amplifiers Formulas

Load Resistance is defined as the cumulative resistance of a circuit as seen by the voltage, current or power source driving that circuit. And is denoted by R_L. Load Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Load Resistance is always positive.

FAQ

What is the Load Resistance?

Load Resistance is defined as the cumulative resistance of a circuit as seen by the voltage, current or power source driving that circuit. Load Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Load Resistance is always positive.

Can the Load Resistance be negative?

No, the Load Resistance, measured in Electric Resistance cannot be negative.

What unit is used to measure Load Resistance?

Load Resistance is usually measured using the Kilohm[kΩ] for Electric Resistance. Ohm[kΩ], Megohm[kΩ], Microhm[kΩ] are the few other units in which Load Resistance can be measured.
