Here's what each part of the name typically refers to:

470K: This indicates the resistance value of the potentiometer. In this case, "470K" means the potentiometer has a total resistance of 470 kiloohms (or 470,000 ohms). This value determines how the potentiometer behaves in a circuit, such as its sensitivity to adjustments.

Potentiometer: This term describes the type of component. A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It allows the user to adjust the resistance manually, thereby changing the voltage output.

Variable Resistor: This is another term for a potentiometer. It highlights the potentiometer's function as a resistor with an adjustable resistance value. By varying the resistance, it can control current flow or voltage levels in a circuit.

WH148: This likely refers to the specific model or series of the potentiometer. Manufacturers often use alphanumeric codes to distinguish between different models or variations within a product line.
