Important things to be noted about Transistors

See this circuit. In this we connected Vcc directly to the base without a resistor. If you connect like this adapter light will go off and circuit won't work properly. Remember that transistor is a current controlled device
NOTE:
● When using transistor first see the ratings of the transistor from its datasheet.
● See the ratings of the device connected in the collector of transistor and match it with maximum Ic of the transistor.
● Remember that transistor is a current controlled device. So connect an appropriate resistor in the base.
● When you check whether the circuit with transistor will work in saturation region measure Vbe first and see if it is in saturation region. I will explain it in H-bridge.
