Hint:The transistor is a fundamental component in the means of electricity. It is a semiconductor device. This device is used for both conducting and insulating electric current and voltage. We can also say that it acts as a switch and an amplifier. And power transistors are transistors that are used for high-power amplification. It is used for handling a large number of power levels in a device or a circuit.
Complete step by step solution:
Note:The power transistors are available in the form of NPN, PNP, and Darlington transistors. The range of the collector current is from \[1\]to\[100A\] and for the operating frequency it ranges \[1\] to\[100MHz\]. Also, the power values range from \[1\]to\[300W\]. The heat sink is constructed by connecting the collector terminal to the base of a metal device.

| Transistor | Power transistor |
| Normal transistors are usually used for amplifying and switching purposes. Whereas power transistors are used in circuits like battery charging and power supply. | Physically powered transistors are larger than normal transistors. And power transistors are capable of carrying more current without melting or burning the transistors. |
| When we apply input current to a pair of terminals we can observe a change in the current in other terminals. This is what normal transistors are capable of, that is they act as a switch or amplifier. | Whereas power transistors act like a heat sink that protects the transistor from heating or burning while carrying more current. |
