Divergence intuition, part 2
In preparation for finding the formula for divergence, we start getting an intuition for what points of positive, negative and zero divergence should look like.
Inductor kickback 2 of 2
We give the inductor's kickback current a path to flow by adding a diode
Inductor kickback 1 of 2
We notice how important it is to give inductor current a place to flow.
Curvature formula, part 2
A continuation in explaining how curvature is computed, with the formula for a circle as a guiding example.

LC natural response derivation 2
Starting from the differential equation, we come up with a proposed exponential solution and plug it into the equation. This gives us a characteristic equation....
LC natural response intuition 2
We can predict the shape of voltage and current in an LC circuit by tracking the motion of charge as it flows back and forth.
Irregular plural nouns | -f to -ves | The parts of speech | Grammar | Khan Academy
The plural of "dog" is "dogs", but what is the plural of "leaf"? Khan Academy's resident grammarian explains.

RC step response 3 of 3 example
An example solution of an RC step response, with real component values.
RC step response 2 of 3 solve
We find the RC step response using the method of Natural + Forced response = Total response.
RC step response 1 of 3 setup
The RC step response is an exponential curve. We set up the circuit and create the differential equation we need to solve. We introduce the technique of Natural...
RC step response - intuition
An RC circuit responds to a step of voltage with a smooth transition between the starting and ending voltage
Capacitor i-v equations
The capacitor i-v equation in derivative and integral form.
Mesh current steps 1 to 3
We solve a circuit by writing Kirchhoff's Voltage Law in terms of "mesh currents." First three steps of four.
