EXAM PAPER 2026 QUESTIONS WITH
SOLUTIONS GRADED 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
⫸ Electrical Test Equipment. Answer: Multimeter
⫸ Multimeter Test Leads. Answer: Red lead = Positive and Black
lead = Negative
