Here the voltage drop across the bases of the transistors will be 1.2V to 1.4V (across the R1+R2 total resistance). The rows will keep appearing as you use them up! Changing the number of poles results in speed change. Basically, the whole power supply will not there at load because of the heating effect as well as other restrictions within the circuit. For maximum power transfer in the public address system, the circuit can be altered by making RL (load resistance) like speaker equivalent toward the source resistance like an amplifier. It is designed to overcome and eliminate the disadvantage of low efficiency in class A amplifiers and distortion in class B amplifiers and utilizes the advantages of both the amplifier classes. The filter circuit allows only the fundamental frequency of the square wave to pass and filter out other high frequency harmonics. Find the load resistance RL that enables the circuit (left of the terminals a and b) to deliver maximum power toward the load. These motors slip with respect to the stator current field.
