2. The expression for capacitor voltage in an RC circuit (assuming no initialcharge) 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*RC5*RC10*RC3. 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 voltageacross the capacitor at t= :0 ms1 ms10 ms4. Derivation: Consider the equation for wa:Wa =(1/LC)- (R/2L)²Oscillation will occur only when this expression is a real number (not animaginary number). Solving, we see that the expression is a real numberwhen (1/LC) > (R/2L)2. If C=0.01µF capacitance and L = 10 mH, whatis the largest value of R for this condition to be true? You will use this resultin the lab.
