Fundamentals of Electrical Engineering
Exam Questions and Answers
Ohm's Law - Answers -V=IR
The relationship of voltage, current, and resistance
Voltage - Answers -The difference in electrical potential energy between two places in a
circuit.
Current - Answers -The rate of flow of charge
Resistance - Answers -A material's opposition to the flow of electric current.
Watt's Law - Answers -The law of electricity stating that power equals voltage times
current or current squared times the resistance.
Energy - Answers -the ability to do work
Work - Answers -force x distance
Power - Answers -the rate at which work is done
Amp-hour - Answers -A measure of electricity
consumption and battery capacity: one amp of current for one hour
series circuit - Answers -An electric circuit with a single path
Parallel Circuit - Answers -A circuit that contains more than one path for current flow.
Kirchhoff's Voltage Law - Answers -The sum of all voltage drops in a series circuit
equals the total applied voltage
Voltage Divider - Answers -The Voltage drop accross any given resistor in a circuit is
equal to the ratio of that resisitor to the total resistance, multiplied by the voltage source
Kirchhoff's Current Law - Answers -The sum of currents entering a node equals the sum
of currents leaving the node
Current Divider - Answers -When Current enters a node it divides inversely proportional
to each branches resistsance
