edmondng said:that resistor is probably just a potentiometer. voltage adjust.
typically; 1 end goes to gnd, 1 end goes to the supply, middle goes to circuit. in this case, it either is adjusting to get VEE -8V or using VEE -8V to get some form of divider or voltage scale to somewhere else
maybe I'm wrong,
VEE is a negative power supply voltage used in electronic circuits. It is commonly used in conjunction with the positive voltage supply VCC to create a power supply with both positive and negative voltages.
A 50k resistor is used to limit the flow of current in a circuit. It is commonly used as a pull-up or pull-down resistor to ensure that a signal is at a known state when no input is present.
VEE is typically connected to the ground or negative rail of a circuit, and a 50k resistor is placed in series with the VEE line to limit the flow of current. This helps to protect the circuit from damage and ensure stable operation.
Without a 50k resistor in a circuit with VEE, the current flow may become too high and potentially damage the components in the circuit. The 50k resistor acts as a safeguard to regulate the current and protect the circuit.
Yes, there are other types of resistors that can be used in place of a 50k resistor in a circuit with VEE. These include other values of resistors, such as 10k or 100k, or different types of resistors like variable resistors or thermistors depending on the specific needs of the circuit.
