THTR 1001 Chapter : Electrical Theory Defined
Document Summary
Electrical current :the flow or movement of electrons through a circuit. Ampere: the unit of measurement of electrical current. Electrical potential: the different in electrical charge between two bodies; measured in volts. Volt: the unit of measurement of electrical potential. Sourcethe origin of electrical potential- such as a battery or 120 volt wall outlet. Load: a device that converts electrical energy into another form of energy: a lamp converts electrical energy to light and heat; an electrical motor converts electrical energy into mechanical energy. Circuit: the pathway way that the current follows as it flows from the negative to positive terminal of the. E = voltage (volts) where e = voltage (volts) R = resistance (ohms) where p = power (watts) Resistance: the opposition to electron flow within a conductor, measured in ohms; the amount of the resistance is dependent on the chemical makeup of the material through which the electricity is flowing.
