What is the form factor for a full-wave rectifier?(a) 1.11(b) 1.57(c) 2.62(d) 0.453The question was asked in unit test.Query is from Semiconductor Electronics topic in chapter Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer»

The correct answer is (a) 1.11

The best EXPLANATION: For a full-wave RECTIFIER,

Irms=\(\FRAC {I_m}{\sqrt {2}}\); Idc=\(\frac {2I_m}{\pi}\)

Form factor=\(\frac {I_{RMS}}{I_{dc}}\)

Form factor=\(\frac {\frac {I_m}{\sqrt {2}}} {\frac {2I_m}{\pi}}\)

Form factor=\(\frac {\pi }{2\sqrt {2}}\)=1.11
