Recall That the Voltage Across a Capacitor Is Given By V_{C}=\frac{1}{C}

Question 7

Multiple Choice

Recall that the voltage across a capacitor is given by VC=1Ci(t) dtV_{C}=\frac{1}{C} \int i(t) d t . Find the formula for VCV_{C} if C=C= .01 farad, i(t) =2t+3i(t) =2 t+3 amperes, and VC(0) =12V_{C}(0) =12 volts.


A) VC(t) =100t2+300t2+1200V_{C}(t) =100 t^{2}+300 t^{2}+1200 volts
B) VC(t) =t2+3t+1200V_{C}(t) =t^{2}+3 t+1200 volts
C) VC(t) =100t2+300t+12V_{C}(t) =100 t^{2}+300 t+12 volts
D) VC(t) =t2+3t+12V_{C}(t) =t^{2}+3 t+12 volts
