(a) The capacitor is initially uncharged at

t = 0. At t = 0+ the gate voltage has

changed state from 1.8 V to 0 V. What is

the initial surge of current at /= 0+.

(b) At 1 = ∞o what is the bias state on the

transistor?

(c) How much energy is dissipated in the

charge movement, and where does the

heat loss occur?
