1. A flux of 1.5 mWb, linking with a 250 turn coil, is uniformly reversed in a time of 0.02 s. Calculate the value of the emf so induced.
2. A coil of 2000 turns is linked by a magnetic flux of 400 μWb. Determine the emf induced in the coil when
(a) this flux is reversed in 0.05 s, and
(b) the flux is reduced to zero in 0.15 s.
For the noninverting op-amp circuit in Figure, the parameters are: A = 105, Av f = 20, Ri = 100 kΩ, and Ro = 100 Ω. - Determine the ideal closed-loop input and output resistances.
8-1. A six-cylinder SI engine, with a compression ratio of rc= 8.5, operates on an air-standard Otto cycle at WOT. Cylinder temperature and pressure when the exhaust valve opens are 1000 K and 520 kPa. Exhaust pressure is 100 kPa and air temperatu..
If the motor in Problem 6-15 is to be driven from a 460-V 50-Hz power supply, what will the pullout torque be? What will the slip be at pullout?
The input resistance of the recorder is unknown andlikely to be variable, but it is greater than 10kΩ. Adeflection of 1 cm per milliampere of cell current with anaccuracy of about ±3 percent is desired. What type of ideal amplifier is best suited ..

Shows an RC circuit with input voltage x (t) and output voltage y(t). The RC circuit is to be used as a low-pass filter - The value of the capacitor used in the design should be as small as possible.
We have a continuous time-domain sinewave signal x(t) = sin(500xt +π / 5). We sample the time-domain signal with sampling period T = 0.2ms and we get the sequence 4n] . If we start sampling at time t = 0 , we will obtain samples at
