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).
Which says Voltage is the difference in electric potential energy per unit charge between two points. Voltage is the work to be done, upon an unit charge to move between two points, against a static electric field.hat is potential energy U(t) = q.V(t). The SI unit of electrical potential is Volt after name of Italian physicist Alessandro Volta (1745 - 1827). Voltmeter is used to measure the potential difference between two points. There is a misconception about potential and voltage.
