Coulomb is the unit of charge flow equal to one coulomb of charge past a given point in one second.

When two potential difference between two charges forces a third charge to move, the charge in motion is called the voltage.

Joule is the unit of electric charge.

Ampere is equal to one joule of work done per one coulomb of charge.

Calorie is the unit of electrical power equal to one joule of energy consumed in one second.

Energy is the rate, per unit time, at which electrical power is transferred.

Power is the ability to do work or apply force to move an object.

BTU or British Thermal Unit is the SI unit of energy and work.

Ohm’s law states that the current passing through the circuit is directly proportional to the voltage, and inversely proportional to the resistance of the circuit.

4.816 Joules is equal to 1 calorie

1 hp is equal to 746 Joules/sec

1 electron/ neutron has a unit charge of $1.6\ x\ 10^{-19}$ coulombs

Resistance increases as the temperature increases.

Aluminum has a resistivity of 17.02 Ω-CM per feet.

A circuit has a 5V supply and resistance of 2 ohms. Therefore, the current flowing is 2500 mA.

A circuit has a power and current of 8W and 16A respectively. The voltage therefore is 2V.

There are 3000 mils in 3 inch.

Pressure in a garden hose that pushes the water acts like Voltage.

Copper has an absolute temperature of 236 degree Celsius.
