NLC FINALS EG2 TERM 2103 EXAM TEST PAPER
2026 COMPLETE QUESTIONS AND ANSWERS
ALREADY PASSED
◉ Voltage. Answer: Electric pressure or electromotive force
(expressed as E)
◉ What increases Voltage. Answer: if the strength of the magnet and
the speed at which it passes the conductor, are increased
◉ Amp. Answer: one coulomb per second. measurement of the
amount of electricity flowing through a circuit (Expressed as I)
◉ what happens if amperage is exceeded?. Answer: the wire will
melt because of the added friction created by the colliding of
electrons in the wire.
◉ ohm. Answer: unit of resistance (Expressed as R)
◉ coulomb. Answer: quantity measurement of elelctrons
◉ Watt. Answer: unit of electrical power (Expressed as P) and is
product of Volts x amps
,◉ 1 amp equals how many coulombs. Answer:
6,250,000,000,000,000,000 or 6.25^18
◉ One horsepower equals. Answer: 746 watts
◉ Ohms Law. Answer: E = I x R (AKA Volts = Amps x Ohms)
◉ Solve For I (intensity of current). Answer: I = E/R
◉ Solve for R(Resistance). Answer: R=E/I
◉ Solve for P (Power/Watts). Answer: p= I x E (watts = amps x volts)
◉ 4 main elements of electrical system. Answer: Generation,
Transmission, Distribution, Substations
◉ The grid. Answer: transmission systems are interconnected and
referred to as this
◉ What is the common purpose of generation facilities. Answer: the
generate power as efficiently as possible
, ◉ Different types of generating facilities. Answer: Nuclear, fossil,
fuel, wind, steam, solar
◉ What range is electricity generated in. Answer: 13,800-24,000
volts
◉ Where is voltage usually stepped up at?. Answer: outside the
generating facility
◉ Small-Scale generation/ Dispersed micro-generation. Answer:
Large industrial and commercial customers purchase micro
generation systems to offset high cost of power during peak load.
◉ Common transmission voltages. Answer:
230kv,345kv,500kv,765kv
◉ sub transmission systems voltages. Answer:
44kv,69kv,115kv,138kv
◉ When is subtransmission systems neccesary. Answer: when
medium-sized blocks of power need to be delivered to distribution
substations at the load center and large transmission systems near
populated areas is sometimes impractical.
