Calculate either the charge, capacitance or voltage across a capacitor using Q=CV.
Calculate the value of a resistor needed to current-limit an LED.
The hammer in any electrical engineers toolbox. Calculate voltage, resistance and current using Ohm's law.
Resistor dividers are a simple, widely-used circuit primitive for reducing a voltage based on a fixed ratio.
Find the closest E-series (e.g. E12, E96) resistor (preferred value) to your desired resistance.
Find the right size wire gauge for a particular current and voltage drop.
The low-pass RC filter is probably the simplist and most used electronic filter. Great for input signal filtering.
