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 has a meaning of a gain while voltage drop - of a loss; voltage is an earned voltage while voltage drop is a lost voltage. If we consider the voltage across an element, voltage means its own voltage (created by the element) while voltage drop means some else's voltage (created by an external source). So, in the first case, the element is active (a source) while in the second case, the element is passive (resistor, capacitor, inductor or something else).
