CERTIFICATION PREP RESOURCE RELIABLE A+
◉ Voltage / Electromotive Force (EMF). Answer: The amount of force
being applied to a circuit to produce an electron flow
◉ Amperage / Current Flow. Answer: The quantity of electricity flowing
through the circuit
◉ Resistance. Answer: The opposition to the flow of electrons offered
by a device or material
◉ Ohms. Answer: The measurement of resistance to current flow
◉ Watt. Answer: The measurement of electrical work done
◉ Forms of Electricity. Answer: Static and Dynamic
◉ Static Electricity. Answer: (1) Electricity at rest
(2) Begins with a build up of either a positive or negative electron
charge. If two negative charges or two positive charges are brought close
together, the objects that hold that charge repel each other. If a positive
,charge is brought within close proximity of a negative charge, the two
objects attract each other
(3) Static electricity is produced by friction and is not easily measured
nor is it controllable or usable
◉ Dynamic Electricity. Answer: A practical form of current flow that is
used in everyday life. This form of electricity is easily produced,
measured, and controlled
◉ Methods of Producing Dynamic Electricity. Answer: Mechanical,
Chemical, Thermal, and Pressure
◉ Mechanical. Answer: Produced by rotating a magnetic field through
another magnetic field
Ex: A Grass Cutter
◉ Chemical. Answer: Produced by surrounding two or metallic plates
with a chemical electrolyte
Ex: A Battery
, ◉ Thermal. Answer: Produced by joining two dissimilar metals and
applying heat
Ex: Thermocouple
◉ Pressure. Answer: Produced by applying pressure to quartz, which
will produce an electron flow
Ex: A Watch
◉ Types of Electricity. Answer: AC and DC
◉ Direct Current (DC). Answer: Current that is a steady flow in one
direction only. It is produced mechanically by a DC generator, or
chemically by a battery
Ex: A Flashlight
◉ Alternating Current (AC). Answer: Current flow that reverses
direction at specific intervals, defined as Hertz / Cycles. It is produced
mechanically by an AC generator
Ex: A TV Screen
