Total Marks: 80 1. Consider the following RC circuit (consider the diode to be ideal). The Capacitor has an initial value of $V_c(0) = 0$. Prove that i) the current through the capacitor is given by, $i(t) = \frac{V_{dc}}{R}e^{-\frac{t}{RC}}$, and ii) the voltage across the capacitor is: $v_c(t) = V_{dc}(1 - e^{-\frac{t}{RC}})$. Marks: 5 + 5 = 10

Compute the break-even point in units. Multiple Choice 4,444. 1,933. 2,900. 5,500. 1,160. Which of the following statements is true? Multiple Choice Absorption costing treats fixed overhead as a period cost. Variable costing treats fixed overhead as a period cost. Managers can manipulate earnings more easily under variable costing by varying the production level. Absorption costing treats fixed overhead as an expense in the period it is incurred. Variable costing excludes all overhead from product costs.
