QuestionAnswer
amperes a unit of electric current equal to a flow of one coulomb per second
circuit diagrams a diagram of a circuit
current electricity dynamic electricity a flow of electric charge
electric circuit an electrical device that provides a path for electrical current to flow
electric current a flow of electricity through a conductor;
electric load the circuit connected to this terminal is the load
electric potential difference Voltage, electrical potential difference, electric tension or electric pressure is the electric potential difference between two points, or the difference in electric potential energy of a unit charge transported between two points
electrical resistance electric resistance: a material's opposition to the flow of electric current; measured in ohms
electrochemical cells An electrochemical cell is a device capable of either deriving electrical energy from chemical reactions
electrodes a conductor through which electricity enters or leaves an object, substance, or region
electrolyte a liquid or gel that contains ions and can be decomposed by electrolysis, e.g., that present in a battery
energy the strength and vitality required for sustained physical activity
ohm the unit used to measure resistance
Ohm's law electric current is directly proportional to voltage and inversely proportional to resistance; I = E/R
potential difference the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
resistance the ability not to be affected by something
resistor a device having a designed resistance to the passage of an electric current.
volt the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.
voltage an electromotive force or potential difference expressed in volts
