    RC circuit with DC source: Kirchhoff’s law, voltage directions, and current flow convention

    I am creating a video in Manim about basic electrical circuits. The circuit under consideration is an ideal RC circuit with a DC voltage source, no energy losses. My reasoning is as follows: When the current leaves the DC source and flows through the circuit, the capacitor starts charging. At...

    I can't understand how to translate this into math: potentiometer as voltage divider.

    Teacher gave us this circuit to analyze and we're supposed to use the voltage divider formulation: \[ V_{R1} = \frac{E\cdot R1}{R1+R2+R3} \] It gives me: \[ V_{R1} = 4.55\] \[ V_{R1} = 6.69\] \[ V_{R1} = 3.75\] The problem is, either I don't know how to interpret these numbers, or I'm not...
