Does a transistor have resistance? - Electrical Engineering Stack Exchange
The external resistor is usually referred to as the load resistor. It could stand for either an electric light, an electric heating element, or, maybe, an electric motor. … , only half of the power output of the voltage source is transmitted to the load. The other half is dissipated as heat inside the source. See more We have to know the term internal resistance. It is the resistance within a voltage source that causes a reduction in the source voltage in … See more The relationship between internal resistance (r) and emf (e) of cell s given by. Where, e = EMF i.e. electromotive force (Volts), I = current (A), R = Load resistance, and r is the internal resistance of cell measured in … See more The potential difference across the poles of a cell when no current is being taken from it is called the electromotive force (EMF) of the cell. … If the external resistance is R and the internal resistance is r, the total … See more External Resistance 1.
