PRACTICE EXAM 2026 TEST PAPER
QUESTIONS AND DETAILED SOLUTIONS
GRADED A+
⩥ What in electrons in a conductor determines whether its flow is poor
or good? Answer: whether or not there contains free electrons in the
orbits of the atoms
⩥ define static electricity. Answer: difference of electrical charge
between two non-conductive surfaces
⩥ what term is used to express the flow of electricity. Answer: Amperes
is the amount of current flowing past a point in the circuit
⩥ define coulomb. Answer: a basic unit of electrical quantity equal to
6.28 billion- billion electrons
⩥ What is the basic unit of electrical pressure. Answer: electron motive
force (EMF) or volts
⩥ If voltage and resistance are known, describe how total current can be
determined. Answer: voltage is divided by the resistance I=E/R
, ⩥ What device other than an actual battery can be used to store energy.
Answer: a capacitor
⩥ Describe the left-hand rule as it pertains to electrical generation.
Answer: This describes the flow of current in a conductor when passed
through magnetic lines of flux. The thumb represents the motion of the
conductor, the index finger represents the line of flux of the magnetic
field, and the middle finger is the resultant current flow
⩥ what trait would allow magnetic lines of flux to flow easily. Answer:
The ease of which the lines of flux follow the material is determined by
the permeability of the material that the lines of flux are directed to flow
through
⩥ Describe the name of a common electrical point that allows circuits to
have a return path to power. Answer: to save wires, all return paths to the
negative electrical potential by using an earth or chassis ground
⩥ what is the result of passing to much current(amps) in a too small
gauge wire. Answer: A larger amount of resistance will slow the rate of
current flow
⩥ Describe the electrical relationship of voltage, current, and resistance
described in Ohm's law. Answer: ohms law is where the electrical
