Question
Download Solution PDFThe arms of a four-arm bridge abcd, supplied with sinusoidal voltage, have the following values :
Arm ab: A resistance of 200 Ω in parallel with a capacitance of 1 μF
Arm bc: 400 Ω resistance
Arm cd: 1000 Ω resistance
Arm da: A resistance R2 in series with a 2 μF capacitance
What are the values of R2 and the frequency respectively at which the bridge will balance?
