Electrodynamic Formulas

Electrodynamics is the area of ​​physics that studies the behavior of moving electric charges.

Here's a list of formulas about this content.

Electric current
Electric current intensity

Electricity Continuity

When there are "path options" in a conductor the current prior to them will be equal to the sum of the currents in each part of the subdivisions.

Electrical resistance
Electrical resistance

Electrical conductance

Resistor Association



In each part of the circuit, voltage (U), resistance (R) and current intensity (i) will be calculated based on what is known about serial and parallel circuits, and to facilitate these calculations it is advisable to reduce or redesign the circuits using resulting resistors for each part.
