Flip flop circuit is made by using two Transistor, in our circuit Q2&Q3. In a flip-flop circuit, at a time only one transistor conduct and other cutoff and when it gets a trigger pulse from outside source then first transistor is cutoff and 2nd transistor conducts, thus output of transistor is either logic-0 or logic-1 and it remains in one state 0 or 1 until it gets trigger pulse from outer source.
The pulse of clap, which is a trigger for flip-flop makes changes to the output state that is complementary (reverse). Output of flip-flop, which is in the low current form is unable to drive relay so we have used a current amplifier circuit by using Q4 that is a common emitter circuit. Output of Q4 is connected to a Relay (Electromagnetic switch) which works like a mechanical switch and it becomes easy for connecting other electrical appliance.
The relay contact is connected to the power line and hence turns on/off any electrical appliance connected all the way through relay.
