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 ( = Electric Potential ) An electric charge alters the space around it. Throughout the space around every charge is a vector thing called the electric field. Also filling the space around every charge is a scalar thing, called the voltage or the electric potential. Electric fields and voltages are two different ways to describe the same thing. (Note on terminology: The text book uses the term electric potential, but it is easy to confuse electric potential with potential energy, which is something different. So I will use the term voltage instead.) Voltage overview The voltage at a point in empty space is a number (not a vector) measured in units called volts (V) . Near a positive charge, the voltage is high. Far from a positive charge, the voltage is low. Voltage is a kind of electrical height. Voltage is to charge like height is to mass. It takes a lot
