Consider a parallel plate capacitor with capacitance 1 F that, initially, when fully charged up, has an electric field with magnitude E 0 = 1
Consider a parallel plate capacitor with capacitance1F that, initially, when fully charged up, has an electric field with magnitudeE0=100V/m (assume the capacitor is disconnected from any power supplies after it is charged). At time t=0 the capacitor is hooked to a 1Mresistor.
- Sketch a plot of the electric field between the plates versus time.
- What is the magnitude of the electric field between the plates at time t=2s?
- Sketch a plot of the fraction of energy initially stored in the capacitor that has been dissipated at time t.
- What fraction of the energy initially stored in the capacitor has dissipated at t=2s?
