Question
A speaker is fed by an amplifier as shown in the schematic and circuit model below. The source voltage (v3) is given as 50 cos(2000nt) V. A coupling capacitor (with capacitance C) is used to block the de current from the amplifier to the speaker. The current in the circuit (i,) is measured as 1.7 cos(2000nt – 9.6°) A. Determine: (a) the power consumed by the speaker. (b) the capacitance C. (c) the power factor seen by the source. Amplifier Speaker Coupling capacitor C 20 2 8 mH
