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) is the potential to do work per unit charge. It is the change of Voltage in space that causes a force on a charge. That force is usually given as force per unit charge and is called the electric field (E). So E = dV / dx, which says, the electric field is the change in voltage per change in position, with the understanding that dx is in the direction of the fastest changing voltage. The source of the force is your question.
