Basic Units of Electricity

The three basic units of electricity are voltage, current and resistance. Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.

Circuit Breaker Failure

A circuit breaker’s job is to limit the amount of current flowing on a circuit so that it doesn’t exceed the rated level. The most common cause of circuit breaker failure is continually overloading it, causing it to trip out or open the circuit.

Surge Protectors

Surge protectors are devised to protect electronic devices from voltage spikes. Surge protectors limit the voltage supplied to an electric device if a voltage spike occurs.

Electrical Safety Advice

Electrical safety begins with knowing some basic facts and good advice about electricity.

Energy Storage

Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.

Electrical Improvements

Improvements and repairs involving electricity should only be performed by licensed professionals. Professional contractors are experienced and knowledgeable, with state approved licenses.

Electromagnetic Interference

Electromagnetic interference is the interference caused by an electromagnetic disturbance affecting the performance of a device, transmission channel, or system.

Dedicated Circuits

A dedicated circuit has an unbroken flow of electricity from the circuit breaker to the point of use. 

How Lighting Changed the World

Artificial lightning is one of the many ways humans have conquered nature.

Primary Energy

Primary Energy is energy that has not undergone transformation to another form, such as coal, oil, natural gas, nuclear energy, solar energy and wind energy.
