A steady current of 3.5 A is flowing through an inductor with 70 volts across it, Find (a) Inductance of the coll if the current falls to zero in 160 msec, (b) Energy stored in the inductor, (c) Number of turns in the inductor for a flux of 50 mWb. Use Thevenin's theorem to simi

Q1) A 100 cm in length cantilever beam subjected to an applied force P. The strain &, at the bottom surface of the beam has a relation with the applied force F is given by &, = 2 x 10-9P where P changes form (0N to 1000KN). The strain can be measured using a120n strain gauge with gauge factor of 2. Design a measuring device that can read the applied load and feeds the required signal to a computer using ten bits ADC accuracy. The system should compensate the temperature effects.

1. The capacitor charges toward the source voltage through the resistor. The flash turns on when the capacitor voltage reaches 8 V. If C = 10 μF, find R such that the flash will turn on once per second.   2. Find the differential equation for the current in the circuit shown below.

Consider the R-C circuit. we idealise the emf to be constant and have zero internal resistance. We begin with capacitor initially uncharged. At initial time t=0, the switch was closed. Answer the questions attached.

Q2/ For the network shown in figure (Q:), the switch has been open for a long time before closing at t-0. Determine an expression for the inductor (L-20mH) current İL(t) for 120. 300 36V 12A 15A lot
