1 Also, be sure that the wick is no longer than 1/8. 2  If it is, extinguish, trim to 1/8, and relight. 3  To minimize wax left on the sides of the jar, burn 3 hours at a time; it is normal for some wax to be left. 4  The amount will vary per color, fragrance and burning conditions.
Voltage. Voltage is electric potential energy per unit charge, measured in joules per coulomb (= volts). It is often referred to as electric potential, which then must be distinguished from electric potential energy by noting that the potential is a per-unit-charge quantity.oltage is electric potential energy per unit charge, measured in joules per coulomb (= volts).
In 1881 the electrical unit we know today, the volt, was named in Voltaâs honor. From the first battery, mentioned above, we can derive a definition of voltage as: Volts-or V-are an electrical measure of energy potential. Voltage can also be thought of as the amount of pressure of electrons that pass from a negative connector to a positive connector.
