Capacitor Current From a Ramp

Random numbersLCMedium

Over an interval, the source voltage changes from −4 V-4\ \text{V} to 5 V5\ \text{V} at a constant rate in 4 ms4\ \text{ms}. Find the current ii into the capacitor during that interval, in milliamperes.

Answers within 2% are accepted. Units with SI prefixes work too, like 0.003 A or 3 mA. Use a minus sign for negative values.

Scratch work goes here. Draw with a mouse, finger, or stylus.
