Therefore, the passive sign convention should be used to find the sign of power: In order to calculate the power consumed (or delivered) by a dependent source, you should 1) calculate the current through and the potential across the source.

But sometimes if the load is a speaker or motor, the speaker or motor may over prt of its cycle generate more voltage than the source. Using source transformation, find the power delivered by the 50 v voltage source in the circuit shown in fig.

You have first to calculate the current flowing in the source, which is the difference between the current in the resistor and the current of the current source. Or the voltage source :

Power will be negative for this element. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance.

The Power Supplied By The Dependent Voltage Source Is −=− =()5 5 0.3068 0.1023 0.1569 Wii23 ( )( ).

Under matched conditions, therefore, half the power generated by the source is delivered to the load and half is lost or dissipated by the source. Power will be positive for this element. 1.153 can be replaced by a voltage source as shown in fig.

Using Source Transformation, Find The Power Delivered By The 50 V Voltage Source In The Circuit Shown In Fig.

The power ps generated by the voltage source v is therefore ps = iv = p + p ′ = v2 / (2 rl ). The total power is equal to the sum of the power used by the individual resistors. Absorbing power for the current source, the current leaves from the positive terminal.

But Sometimes If The Load Is A Speaker Or Motor, The Speaker Or Motor May Over Prt Of Its Cycle Generate More Voltage Than The Source.

Resistors dissipate energy in the form of heat, and the rate at which they dissipate energy is called power. Hence, the active sign convention should be used: If 240 v is the rms amplitude of the voltage source, you have:

The Efficiency Of Maximum Power Transfer Is, Consequently, Only 50%.

For the voltage source the current enters from the positive terminal. Or the voltage source : And the power is :

P = V X × I = 2 × 1.5 = 3 W.

Ohm’s law for the rms ac is found by dividing the rms voltage by the impedance. There are several ways of calculating the power of resistors. The power supplied by the 6 v voltage source is −=− =−6 6 0.4091 2.4546 wi1 ( ).
