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).
Voltage. Voltage is the measure of the strength of an electrical source (for a given current level). Rechargeable batteries for power tools generally contain cells with a voltage of 1.2V, 1.5V or 3.6V. Manufacturers utilize these cells to produce batteries that can have a voltage of anywhere between 3.6V and 48V.atteries that have a voltage between 14.4V and 36V are manufactured for use on heavier duty tools such as cordless hammer drill drivers, cordless angle grinders, and cordless circular saws. The most common voltage used amongst manufacturers (due to its weight, cost, and potential power output) is 18V.
