1. The problem statement, all variables and given/known data A simple series circuit consists of a 150 ohm resistor, a 25 V battery, a switch and 2.5 pF parallel plate capacitor(uncharged initially) w/ plates 5mm apart. The switch is closed at t=0. What is the maximum electric flux and maximum displacement current through the capacitor? 2. Relevant equations 3. The attempt at a solution Maximum flux will be achieved when the capacitor is fully charged, at Vc = Vbat Vc = 25 V Q = (2.5*10^-12)(25) = 6.25 * 10 ^-11 C Electric flux = EA cos(theta)= qin/epsilon 6.25*10e-11 / 8.85e-12 = <b> 7.06 Vm^2 </b> Displacement current = 8.85* 10e-12 * dFluxElectric/dt which = I/epsilon I need to find the Imax, so I used the formula for the charging of a capacitor: Q = Qmax(1-e^-t/RC) I = -dQ/dt = -Qmax/RC * (1-e^-t/RC) RC = 3.75 e-10 the maximum I is Qmax/RC Qmax is calculated above to be 6.25e-11 so Imax is .167 A so I think the maximum displacement current is .167 A Did I do this right?
