2. The expression for capacitor voltage in an RC circuit (assuming no initial
charge) when DC voltage is applied is vc(t) = V(1- e-(t/RC)). Assume V,
= 10 V, C = 50 µF, and R 100 N. Calculate capacitor voltage when t =:
1*RC
5*RC
10*RC
3. The voltage across an inductor when a DC voltage is switched on is vi(t) =
Ve-(t/L/R). Assume V, = 10 V, L= 1 mH, and R = 1 N. Find the voltage
across the capacitor at t= :
0 ms
1 ms
10 ms
4. Derivation: Consider the equation for wa:
Wa =
(1/LC)- (R/2L)²
Oscillation will occur only when this expression is a real number (not an
imaginary number). Solving, we see that the expression is a real number
when (1/LC) > (R/2L)2. If C=0.01µF capacitance and L = 10 mH, what
is the largest value of R for this condition to be true? You will use this result
in the lab.
