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, V. 1  Voltage is a measure of the energy carried by the charge. 2  Strictly: voltage is the 'energy per unit charge'. 3  The proper name for voltage is potential difference or p.d. for short, but this term is rarely used in electronics.oltage attempts to make a current flow, and current will flow if the circuit is complete. Voltage is sometimes described as the 'push' or 'force' of the electricity, it isn't really a force but this may help you to imagine what is happening.
