All right!Jacobi wrote:Awesome! You next.UTF-8 U+6211 U+662F wrote:Jacobi wrote:Write the voltage drop equations for a capacitor and a resistor.
Describe the behavior of an RC circuit which is a) charging and b) discharging.

Describe the behavior of an RC circuit which is a) charging and b) discharging.
a) The voltage through the resistor starts high and decays exponentially as the capacitor becomes saturated. The charged capacitor has an extremely high voltage drop.
b) The voltage through the resistor starts high and decays exponentially as the capacitor discharges. The capacitor acts as a voltage source in the absence of other sources.

Not ideal ones but they can be approximated; however, real-life sources have a limited amount of charge (which can be measured in ampere-hours) and have internal resistance that sometimes needs to be accounted for.
