For parallel capacitors a resistor is needed in the loop when I run a simulation but I haven't seen this in any circuits, is it not needed in a real circuit?
A resistor is used in a parallel capacitor simulation to limit the flow of current and prevent damage to the capacitor. It also helps to stabilize the voltage across the capacitor.
Technically, yes, you can simulate a parallel capacitor without a resistor. However, it is not recommended as it can lead to unstable results and potential damage to the circuit.
The resistor value should be chosen based on the desired current flow and the capacitance of the capacitor. It is recommended to consult a circuit designer or use online tools to determine the optimal resistor value.
If the resistor value is too high, it will limit the current flow too much and the capacitor will not charge properly. If the resistor value is too low, it will allow too much current to flow and may damage the capacitor.
Yes, it is important to consider other components such as the power supply, the load, and the connecting wires in a parallel capacitor simulation. These can all affect the performance and accuracy of the simulation.
