1)As can be seen in the figure, there is a motor attached to one plate of the capacitor which makes the capacitor variable in time. Find the current flowing in the circuit if the capacitor is connected to a DC Voltage. Current I = ௗ௤ ௗ௧ and q = CV where q = charge in the capacitor Therefore, ܫ = ௗ௤ ௗ௧ = ݀ ஼௏ ௗ௧ = ௏ௗ஼ ௗ௧ = ܸܥ ( ଵି௖௢௦௪௧ ) ௗ௧ = ܸܥ ݓݏ݅݊ ( ݓݐ ) 2)The current-voltage characteristics of a non-linear resistor are governed by equation:- i =(2 -1 ) vin (0 7 -1 V -1 ) vin 2 +(0 4 -1 V -2 ) vin 3 0 3( - 1 V -3 ) vin 4 . If a voltage vin (shown below) is applied across the terminals of the resistor, which of the following waveforms shows the current that would flow through it?

From the equation, since the voltage Vin is “small” [Range : 0.95V to 1.05V], the terms that involve Vin 2 , Vin 3 , Vin 4 respectively, can be assumed to be insignificant. Hence the dominant term is “2Vin”. Thus the current is almost
