Two metallic terminals protrude from a device. The terminal on the left is the positive reference for a voltage called Vx (the other terminal is the negative reference). The terminal on the right is the positive reference for a voltage called Vy (the other terminal being the negative reference). If it takes 1 mJ of energy to push a single electron into the left terminal, Determine the voltages Vx and Vy.
For the current shown in the figure below, find the charge waveform
and then find the value of charge at t=2 sec and t=10 sec

Note that the charge Q all came from the power
supply through the resistor ) During the chargingthe
power delivered by the supply is P = IV The energy
delivered by the supply is powerxtime, or since lis
varying during charging E=V int I dt=VQ since I is just
charge per time. Compute the energy E = VQ

Transient RC response. Consider the following circuit with R-1 k2, C=0.1 µF and V-10
Volts. Initially the capacitor is discharged (Vc-0) and the switch is open as shown, so no
current flows. At time t-0 the switch is closed, allowing current to flow through the resistor
and charge up the capacitor.
