1. The current in an inducer is given by function l(t) = 0.3e2t - 0.152 + 2.0. If your self-inductance is 325 mH. Calculate the induced inducer inducer inducer fort = 1.0 s. 2. A LR circuit is constructed and it is observed that to reach 0 to 0.75 of the maximum current value takes 2.56 ms. Calculate the circuit time constant and resistance if L = 31.0 mH. 3. The electromagnetic wave electromagnetic field is given by Ē = 7.2 x 106 ) V/m. If the spread speed is 3 x 108 K, calculate the magn'-wave field vector. 4. A candle is 14 cm from a concave mirror of 35 cm from a curvature radius. Calculate (a) focal distance of the mirror, (b) where the sail image will be located and (c) tell if the image will be right or reversed. 5. A glass block (n = 1.6) is shown in the figure, the cu'al is surrounded by air. A lightning beam enters the block through the left face making an angle of incidence 01 and emerges from the right face parallel to the base of the block. Calculate the angle of incidence. 1 457
