Max power transfer theorem and kirkchhoffs laws - Lab Report Example

Irrespective of the high dissipated power because of the lower total resistance, it happens that the dissipated amount of power would be reduced. This paper reports on an experiment done to investigate the Maximum power transfer Theorem. A laboratory power supply was connected in series using a fixed 100 ohm resistor. A decade resistance box was connected across the simulated source of voltage to function as the variable resistor load, RL. The RL was temporarily removed and connected to the meter to measure the voltage across the 100 ohm resistor and the power supply.

The power supply was adjusted until the voltmeter reads 1 v. The voltage setting was not adjusted from this point. The simulated voltage in the open circuit was found to be 1V. RL was reconnected. The current and the voltage was measured through connecting a voltmeter and ammeter as shown in diagram 1, for a number of values of resistance, RL, from zero to 200 ohms. The readings were recorded in table 1 under the results section of this report. The voltage was half the open circuit value at 200 ohm.

This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors. The load current was half the short circuit value at 200 ohm. This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors. The load resistance for which power is dissipated in the load VLIL at the maximum is 200 ohms. This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors.

The obtained result agrees with the maximum power transfer theorem, which argue that the dissipated power in the load would be maximum whenever the load is equal to the resistance source. The obtained results in the study were in agreement with the theorem of maximum power
