The voltage applied to an R-L circuit at t = 0 when switch is closed is 100 cos (100 t + 30°). The circuit resistance is 80 Ω and inductance is 0.6 H (in which initial current is zero). What is the maximum amplitude of current flowing through the circuit?

How many distinct binary trees can be constructed with three nodes?

For determining the network functions of a two-port network, it is required to consider that

Consider the CMOS circuit shown, where the gate voltage V_G of the n-MOSEFT is increased from zero, while the gate voltage of the p-MOSFET is kept constant at 3 V. Assume that, for both transistor, the magnitude of the threshold voltage is 1 V and the product of the transconductor parameter and the (W/L) ratio, i.e. the quality μC_0x(W/L), is 1mA. V^-2.

Estimate the output voltage V₀ for V_G = 1.5 V. [Hint: Use the approximate current voltage equation for each MOSEFT
