You are expected to read required equipment\'s datasheets and do analytical calculations for given circuit (Circuit 1) to find: Maximum average power that can be delivered to the load,

Solution

the darlington transistors TIP 122 and TIP 127 are complementary, so

the voltage of the charge is approx.= 7.5V

the maximum current that suports both transistors in AC is 8A.

transistors form a power stage and when one conducts the other is cut off, thus all the current flows through the load.

the maximun power at the load is: P=VI=8A*7.5V=60W
