This is amplifier circuit diagram using transistor. this circuit can make maximum 200 watts. using 50 voltage and 4 amperes.

This is a 5-voltage circuit diagram for the Bluetooth card or charging 4.2-volt battery. or anywhere we want. we can use 7805 to make 5 volts. but 7805 can make half amperes. Sometimes we need more amperes. here used tip41c transistor. this transistor can make a maximum of 6 amperes. if we use 12 voltage 5 amperes in the 7805 then we will get 5 voltage half amperes. but if we use this circuit then we will get 5 volts 5 amperes.

This is a circuit diagram to make strong 5 voltage. normally we use 7805 to make 5 voltage for audio Bluetooth cards or others. but 7805 makes 500ma amperes. but sometimes we need 2 amperes. then we can use this circuit. this circuit can make 6 amperes. TIP41c is an NPN transistor. this transistor runs with 100 volts and 6 amperes. the transistor will make hot. for this, we use a heatsink.
