what is the difference between vcc and vee?

i searched this question on google but i didn't understand it. can someone give me a simplified explanation please??

You must not have looked too hard. The first hit when I googled

"transistor Vcc Vee" was

thanks oobleck

Vcc and Vee are voltage supply terms commonly used in electronic circuits. Let me give you a simplified explanation:

1. Vcc: Vcc stands for "collector voltage" and is commonly used in bipolar transistor circuits, especially in digital logic circuits. It refers to the positive supply voltage that is connected to the collector terminal of the transistor. In other words, Vcc represents the voltage level that powers the circuitry.

2. Vee: Vee, on the other hand, stands for "emitter voltage" and is also used in bipolar transistor circuits. It refers to the negative or ground supply voltage that is connected to the emitter terminal of the transistor. Vee represents the voltage level that acts as a reference or common ground for the circuit.

To summarize, Vcc is the positive supply voltage connected to the collector terminal, while Vee is the negative or ground supply voltage connected to the emitter terminal.

Understanding these terms is essential when working with transistor circuits, especially in determining biasing levels and ensuring proper voltage levels for the circuit to operate correctly.
