Faraday's Law
Faraday's laws of electromagnetic induction state:
i) An induced e.m.f is setup when the magnetic field linking that circuit changes
ii) The magnitude of the induced e.m.f in any circuit is proportional to the rate of alter of the magnetic flux linking the circuit.
An electroscope charged WITHOUT contacting a charged body is charged by: a) Induction b) Conduction c) Convection d) Insulation Ans: An electroscope char
Since dc motors of various types are used extensively in control systems, it is essential for analytical purposes that we establish a mathematical model for the dc motor. Let us co
Q. What is Idss. What are the conditions for its maximum value? The term 'Idss' refers to saturation condition of the Drain current. From the above graph it's clear that as the
Q. Let v(t) = Vmax cos ωt be applied to (a) a pure resistor, (b) a pure capacitor (with zero initial capacitor voltage, and (c) a pure inductor (with zero initial inductor current)
Explain the Johnson Counters? The Johnson counters are a variation of standard ring counters with the inverted output of the last stage fed back to the input of the first stage
Q. In a CD amplifier,given Rs =4k?, µ=50 and rd= 35k μ. Find the voltage gain Av. The voltage gain, A v = Vo / V i = µR s / (µ+1) R s + rd = 50*4* (103 )/ (50+1)*4*103
