Learn how to use the right-hand thumb rule to find the direction of the magnetic field around a current-carrying wire.

Current that keeps changing is direction is called alternating current, (AC) whereas the one that never changes its direction is called direct current (DC). Power can be transmitted with low …

Kirchhoff's Current Law says the currents flowing into a node must add up to zero. Created by Willy McAllister.

Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge. We can insert these definitions into the equation for power:

Ohm's Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm's Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you …

Correct, current is a description of the rate of flow. The current flow in ANY circuit is a function of the voltage applied and the total resistance of the circuit.

It is mentioned here because it was a "current thing" when the lesson was made a few years ago. Because artifacts are often artistic expressions, discussion of them is right and proper in a …

Wprowadzenie do obwodów elektrycznych prądu stałego You may have heard of electric current. But what exactly is it? In this lesson, we will explore this and figure out how do we measure …

And maybe oil drops off and people have layoffs in Texas, so housing prices go down in Texas. Or they have layoffs in Michigan, so housing prices go down there. But nationwide, housing …
