A very handy Ohm's Law graphic when calculating the value of components in a circuit.

Think I'm going to re-draw this and keep it near my desk :>.

@rek I wonder why it uses E for volts, I've only seen equations use V

A better version of the graphic :>, sourced from my textbook.

@rek shouldn't the book's version have P instead of W in the center circle?

@rek why is voltage represented with an E?

E is the electric field.
V is the voltage.

Seeing E for the voltage gave me a shock ⚡

@ranfdev Power is represented by E (short for electromotive force). Context: This is in a textbook for Amateur Radio study.
