Could you elaborate?Elliot_Bennett said:How can taking voltage and current readings from an AC supplied CCT with either a resistive, capacitive or inductive load (gradually increasing the load for each) show the difference in phase angle between voltage and current for each component? Many thaks for any help.
I recently did an experiment whereby an AC generator supplied a capacitive, resistive or inductive load, for each readings of voltage and current were taken from the AC Generator showing how it reacted to various levels of RLC load. On a capacitive load as the load value was increased the current and voltage both increased, on an Inductive load as the load was increased the voltage rose and current fell and on a Resistive load as the load was increased voltage rose and current dropped (but showed less change than a purely inductive load).cnh1995 said:Welcome to PF!

So did you use a series RLC circuit and changed the componemt values one at a time or did you use purely resistive and purely reactive circuits?Elliot_Bennett said:I recently did an experiment whereby an AC generator supplied a capacitive, resistive or inductive load, for each readings of voltage and current were taken from the AC Generator showing how it reacted to various levels of RLC load.
What do you mean by 'load' here? Did you increase the capacitance?Elliot_Bennett said:On a capacitive load as the load value was increased the current and voltage both increased, on an Inductive load as the load was increased
No we did not use a series RLC circuit. Purely resistive, purely capacitive and purely inductive circuits with only the relevant component in each circuit, for each the value of the inductor, capacitor or resistor was increased. I.E for resistive from 50-450 ohms at 50 ohm intervals.cnh1995 said:So did you use a series RLC circuit and changed the componemt values one at a time or did you use purely resistive and purely reactive circuits?

To understand what's going on you need to lock the excitation,, ie switch the voltage regulator from "Auto" to "Manual". Otherwise you're just testing the voltage regulator.Elliot_Bennett said:AC generator supplied a capacitive, resistive or inductive load, for each readings of voltage and current were taken from the AC Generator showing how it reacted to various levels of RLC load
Phase angle in RLC circuits is the measurement of the phase difference between the voltage and current readings. It indicates the relationship between voltage and current and can be used to determine the impedance of the circuit.
Phase angle is calculated by taking the arctangent of the ratio of the reactance to the resistance in the circuit. It can also be calculated by finding the difference in the phase angles of the voltage and current readings.
The phase angle in RLC circuits is important because it helps to determine the power factor of the circuit. A low phase angle indicates a more efficient circuit with a higher power factor, while a high phase angle may indicate a less efficient circuit with a lower power factor.
The phase angle can change depending on the type of RLC circuit. In a series RLC circuit, the phase angle can range from 0 to 90 degrees. In a parallel RLC circuit, the phase angle can range from 0 to -90 degrees. In a resonant RLC circuit, the phase angle is typically 0 degrees.
The phase angle can be used to troubleshoot problems in RLC circuits by comparing the voltage and current readings. If the phase angle is too high or too low, it could indicate an issue with the circuit, such as a faulty component or incorrect wiring. Additionally, monitoring the changes in the phase angle over time can help identify any changes or irregularities in the circuit.
