The most fundamental formulas in electronics are Ohms Law and Watts Law:

Ohms Law: V = I*R
Watts Law: P=I*V

P=Power in Watts​
I=Current in Amps​
V=Voltage in Volts​
R=Resistance in Ohms​

With the two laws and a little algebra, you can calculate any of these variables if you have two of the other variables.

This resource is a printable version of this handy chart that has done the algebra and shows how to calculate Power, Current, Voltage or Resistance from any two of the 4 properties.
