ELECTRICAL INSTRUMENTATION EXAM QUESTIONS
WITH VALIDATED ANSWERS 2026 – 2027 .
Watt's Law - correct Answers -tells how much power is being used and is equal to volts times the
current flow in the circuit
Watt - correct Answers -A measure of electrical power equal to one joule of work per second.
voltage drop - correct Answers -the voltage that is dropped across a load or resistance.
Voltage - correct Answers -electrical pressure, the force which causes current to flow through a
conductor.
Volt - correct Answers -the unit of electric potential (pressure)- the difference of electric
potential existing between two points in an electrical circuit.
source - correct Answers -provides the voltage and current that the circuit needs.
short circuit - correct Answers -A connection that allows current to take the path of least
resistance. an overcurrent that greatly exceeds the normal full-load current of the circuit.
series circuits - correct Answers -the components (resistors or loads) in a series circuit are
connected in successive order
with the end of one joined to the end of the next
Resistance - correct Answers -the opposition to the flow of current and limits the amount of
current in an electrical circuit.
1
, open circuit - correct Answers -when any part of the path is open or broken and there is no
continuity in the conducting path.
Ohm's Law - correct Answers -explains the relationship of voltage, current, and resistance in a
circuit. The current flowing through an electrical circuit is proportional to the voltage across it
and inversely proportional to the
resistance.
Ohm - correct Answers -unit of electrical resistance
load - correct Answers -the part of an electrical circuit in which work is accomplished.
Kirchhoff's Laws - correct Answers -[circuits] 1. the sum of current flowing into a junction must
equal the sum of the current leaving at any junction, and 2. the sum of voltage sources = the sum
of voltage drops around a closed-circuit loop. the algebraic sum of all the voltage rises and
voltage drops equals zero. This means that the total applied source voltage is equal to the sum of
all the voltage drops around any one path of an electrical circuit.
Ground or Common - correct Answers -a conducting connection between an electrical circuit
and the earth, or some other conducting body. The point of reference that every electrical circuit
has.
Direct Current (DC) - correct Answers -Current that does not reverse its direction of flow.
current that flows from positive to negative poles.
current - correct Answers -the movement of electrons through a conductor. Measured in amps. In
a parallel circuit, it takes
two or more paths.
Ampere - correct Answers -a unit of electric current equal to a flow of one coulomb per second.
