The Rift Between Tesla and Edison - One Minute History_1080
In 1884, engineer Nikola Tesla was hired by Thomas Edison’s Headquarters in New York City. Tesla idolized Edison, but the two had one fundamental disagreement; Edison favored DC, Direct Current, in which electricity flows in one...

AC and DC supply _ GCSE Physics
Electrical supplies can be direct current or alternating current. It's referred to as AC/DC but not rock band of course. If the current flows in one direction it is called direct current. Batteries supply DC current to most of your...

How does an Electric Motor work? DC Motor explained
DC Motor explained - in this video we look at how does a dc motor work to understand the basic working principle of a DC motor. We consider conventional current, electron flow, the winding, armature, rotor, shaft, stator, brushes, brush...

Electromagnets and Electromagnetic Induction _ GCSE Physics
When a current flows through a wire it causes a magnetic field to be produced around the wire. For a single piece of wire, the magnetic field is made up of concentric circles around the centre. If you coil the wire up however, the...

Khan Academy: Ac Analysis Superposition
We break a sinusoidal input voltage into two complex exponentials. Using superposition, we can recover the complex output signals and reassemble them into a real sinusoidal output voltage. [7:19]

Khan Academy: Ac Analysis Intro 1
Solving circuits with differential equations is hard. If we limit ourselves to sinusoidal input signals, a whole new method of AC analysis emerges. [6:42]
