Answers
(With A+ Grades Guarantee)
, What is the most important law applicable to the study of Ohm's Law (V = I x R)
electricity?
What are the elements of Ohm's Law? Voltage (v), Current (I), Resistance (R)
What are 4 sources of electrical power? Mechanical (generator/ alternator), Chemical (battery), Photoelectric (light),
and Thermal (heat)
What does an electrical circuit consist of? A source of electrical pressure (EMF), Resistance in the form of an energy
consuming electrical device(light bulb), Conductors to provide a path for
electron flow (wires). (a Power source, a load, and a conductor connecting
the load and the power source)
What represents capacitance in an AC circuit? A Capacitor
What is the function of a capacitor? To store electricity
What is Inductance? When voltage is induced by magnetic flux lines in a coil in an AC circuit. The
induced voltage is opposite in direction to the applied voltage, and opposes
any change in the alternating current.
What is impedance? The total opposition for AC to flow caused by the combined effect of
resistance, inductive reactance, and capacitive reactance in an AC circuit.
What is the unit of measurement of power in a DC circuit? The Watt.
amp x volt = watt,
how many watts are in 1 horsepower? 746 watts
What is a kilowatt? 1000 watts
In a DC circuit, what occurs when voltage is increased, There will be an increase in current
while the resistance remains the constant?
What are the 3 types of DC electrical circuits? They are Series circuits, Parallel circuits, and complex circuits (series-
parallel)
A 24 volt lead-acid battery has how many cells, and what is It has 12 cells, and each cell is rated at 2 volts
each cell rated at?
