Measurements


1. VOLT (also called Voltage)

Measures the pressure or force that pushes the electric current forward through the conductor.

A higher voltage means more power with bigger pushes.


Car batteries = 12 volts Most air conditioners and clothes dryer = 240 volts Normal electric wall sockets that power your tools = 120 volts


2. AMPERE (also called AMP)

Measures the strength of an electric current.


A higher amp indicates a greater number of electrons and a stronger current. A blow dryer at 12 amp must have a cord that is twice as thick as a 6 amp. Otherwise, the cord might heat up and start a fire or melt. So to carry more current, you need a thicker cord or wire.


Milliampere: is 1/,000 of an ampere; the current used in facials and scalp treatment.

An ampere current would be too strong for facials and scalp treatment. If used for those, it would damage the skin or body. (Think of music blasting, if you want it lower, think of milliampere)


3. OHM

Measures the resistance of an electric current.

Current will not flow through a conductor unless the force (volt) is stronger than the resistance (ohms).


4. WATT (also called Wattage)

Measures how much electric energy is being used in one second.

A 40 watt light bulb uses 40 watts of energy per second


Kilowatt: is 1,000 watts

The electricity in your house is measured in kilowatt per hour (kWh).
