bridge have been used for measurement of capacitance in a circuit.Today there is instrumentation available that makes use of these bridges in real life such as that can measure the quality of electrical insulation at power frequency as well as in touch-sensitive sensors. This paper presents an understanding of bridges to measure capacitance‚ their real life implementation ‚ various errors in measurement and the required cautions to avoid errors. I.
