What can be used to measure capacitance, inductance, and resistance with precise accuracy?

The use of AC bridges to measure capacitance, inductance, and resistance with precise accuracy is well established in the field of electronics. An AC bridge operates by balancing an unknown component against known reference components using alternating current. This technique allows for high-precision measurements because it compensates for factors such as frequency dependence and component non-linearity, which can affect measurements in other types of devices.

AC bridges typically consist of several resistors and capacitors arranged in a way that, when the circuit is balanced, allows for accurate calculations of the properties of the unknown component based on the known values. This method is particularly favored in laboratory settings and industrial applications where accuracy is paramount, especially when dealing with high-frequency signals.

Devices like resistance meters and digital multimeters can measure resistance, and some digital multimeters also have functions to measure capacitance and inductance, but they do not generally reach the same level of precision as AC bridges in these specific measurements. Waveform analyzers, on the other hand, are primarily used for analyzing waveforms and signal characteristics rather than directly measuring the fundamental properties of passive components like capacitance or inductance.
