Call the electrician
He decided that electrical charges should be designated positive and negative.
Benjamin Franklin
The ancient Greeks called naturally occurring magnets this.
Lodestones
This famous inventor went up against Tesla in the War of the Currents.
Thomas Edison
An object that loses electrons develops this sort of charge.
Positive
Benjamin Franklin discovered that this stormy phenomenon is simply static electricity on a larger scale.
Lightning
He had an electrical unit named after him because he invented the first battery.
Alessandro Volta
In magnetic materials, the areas where the magnetic orientation of atoms align are called these.
Domains
The circular path that electrical current flows through is called this.
A circuit
The ancient Greeks discovered that they could generate static electricity by rubbing this substance with fur.
Amber
These are able to transmit electrical current with zero resistance.
Superconductors
A twitching frog's leg made him famous.
Luigi Galvani
The strength of magnetic fields are measured in these units.
teslas
This is how hard it is for electricity to move through a conductor and is measured in ohms.
Resistance
Charging by contact is often called this.
Charging by conduction
These devices, now mandatory in all new homes, are designed to cut the electricity if a circuit gets overloaded.
Circuit breakers
He popularized alternating current.
Nicola Tesla
The direction of a magnetic field induced by an electrical current can be found using this rule.
The right hand rule
The number of times alternating current switches direction per second is measured in these units.
Hertz
This occurs when a charged object comes near a neutral object.
Charging by induction
Electrical potential is usually referred to as this.
Voltage
He realized that electricity and magnetism were two sides of the same force he called electromagnetism.
James Clerk Maxwell
This English scientist was the first one to use magnets to generate electricity.
Michael Faraday
These are the 2 types of circuits electrical current can flow through.
Series or parallel
If the arrows used to represent an electrical field point outward, it indicates what about the field.
The field is positive.
Hans Christian Oersted found that he could use an electrical field to affect these.
Magnetic compasses
