6 FAQs about [Capacitor bridge resistance is zero]
Why is stray capacitance a problem in sensitive AC bridge circuits?
A potential problem in sensitive AC bridge circuits is that of stray capacitance between either end of the null detector unit and ground (earth) potential. Because capacitances can “conduct” alternating current by charging and discharging, they form stray current paths to the AC voltage source which may affect bridge balance: (Figure below)
What is the difference between AC bridge and DC null detector?
Like DC null detectors, its only required point of calibration accuracy is at zero. AC bridge circuits can be of the “symmetrical” type where an unknown impedance is balanced by a standard impedance of similar type on the same side (top or bottom) of the bridge.
What is a parallel resistance capacitance bridge?
A parallel-resistance capacitance bridge has a standard capacitance value of 0.1F. Balance is achieved at a supply frequency of 100Hz when R 3= 10k, R 1=375k , and R 4=14.7k. Determine the resistive and capacitive components of the measured capacitor and its dissipation factor (D-factor).
Can a bridge be used to measure unknown impedances?
As we saw with DC measurement circuits, the circuit configuration known as a bridge can be a very useful way to measure unknown values of resistance. This is true with AC as well, and we can apply the very same principle to the accurate measurement of unknown impedances.
How does a simple capacitor bridge work?
Fig.1: (a) Simple Capacitance Bridge Working Principle of Capacitance Bridge When the detector indicates null, the voltage drop across Cs must equal that across Cx, and similarly, the voltage across Q must be equal to the voltage across P. therefore,
Are AC bridge circuits symmetrical or nonsymmetrical?
AC bridge circuits can be of the “symmetrical” type where an unknown impedance is balanced by a standard impedance of similar type on the same side (top or bottom) of the bridge. Or, they can be “nonsymmetrical,” using parallel impedances to balance series impedances, or even capacitances balancing out inductances.
