Capacitor Equations and Current Pulse Analysis

The video tutorial explains the behavior of a capacitor in a circuit with a current pulse. It begins by introducing two forms of capacitor equations and setting up a circuit with a current source and a capacitor. The tutorial then analyzes the circuit during three time periods: before, during, and after the pulse. It uses integral equations to calculate the voltage across the capacitor, showing how the voltage ramps up during the pulse and remains constant afterward. The tutorial provides a clear understanding of how capacitors integrate current over time.
