1While working in an electrical workshop under the MSBSHSE Vocational Electrical Technology syllabus, the first action after a person receives an electric shock and remains in contact with a live conductor should be to:
A.Pull the victim away with bare hands immediately
B.Isolate the supply or separate the victim using a dry insulating object, then begin first aid
C.Splash water on the victim to cool the burns
D.Wait for the circuit breaker to trip on its own
Explanation: Standard electrical first-aid practice is to remove the hazard safely: switch off the supply if possible, or separate the victim with a dry non-conducting object (dry wood, rubber gloves, insulated tools). Touching the victim with bare hands while still energised can electrocute the rescuer. Only after isolation do you check breathing/circulation and apply artificial respiration as needed.
2Which portable instrument is most commonly used by wiremen to quickly check whether a terminal is live before working on it?
A.Earth resistance tester only
B.Neon tester (line tester)
C.Hydrometer
D.Tachometer
Explanation: A neon tester (line tester) indicates the presence of AC mains voltage on a conductor and is a standard first check tool in domestic and industrial wiring practice. It does not replace proper isolation and testing procedures, but it is the common live-presence indicator taught in Electrical Technology tool kits.
3For an electrical fire involving energised equipment, the preferred extinguishing approach taught in vocational safety units is to:
A.Use water jets as the first response
B.Isolate the electrical supply if safe, then use a suitable extinguisher (e.g., CO₂ or dry powder) rated for electrical fires
C.Throw sand only after pouring oil on the flames
D.Cover the fire with a metal sheet while equipment remains live
Explanation: Electrical fires require de-energising the circuit when safe, then using extinguishers appropriate for Class C / electrical fires (CO₂, dry chemical). Water can conduct electricity and cause shock if applied to live equipment. Vocational syllabi emphasise fire extinguishers and electric-fire precautions alongside shop discipline.
4In standard electrical drawing practice, the symbol of a normally open push-button typically represents a control device that:
A.Remains closed until manually forced open permanently
B.Closes its contacts only while the button is pressed, then reopens
C.Measures earth resistance continuously
D.Steps voltage up by turns ratio
Explanation: A normally open (NO) push-button has open contacts at rest; pressing it momentarily closes the circuit for start/stop control schemes. Reading electrical symbols and drawings is an explicit FA Electrical Wiring learning outcome.
5Which tool combination is correctly matched for common electrical workshop tasks?
A.Hacksaw — measuring insulation resistance
B.Combination pliers — gripping, bending, and cutting conductors as appropriate
C.Plumb bob — measuring line current
D.Tenon saw — checking phase sequence
Explanation: Combination pliers are multi-purpose hand tools for gripping, bending, and cutting wires in wiring and appliance work. Insulation resistance needs a megger; current needs ammeters/clip-on meters; phase sequence needs a phase-sequence indicator.
6Artificial respiration is indicated in electrical accident first aid primarily when the casualty:
A.Has only a small superficial burn but is fully conscious and breathing normally
B.Is not breathing adequately after the supply has been isolated and the airway is checked
C.Complains of mild tingling after a static discharge from clothing
D.Has a fully intact circuit still energised and must not be touched under any circumstances without isolation — wait indefinitely without acting
Explanation: After safe isolation, if breathing has stopped or is inadequate, artificial respiration methods taught in vocational safety modules (and general first aid) are used while awaiting medical help. Conscious, normally breathing casualties need monitoring and burn care, not forced artificial respiration.
7A series test lamp is used in wiring work mainly to:
A.Measure earth electrode resistance in ohms to one decimal place
B.Indicate continuity or presence of supply and help locate open circuits in a practical way
C.Rewind transformer primary coils automatically
D.Set the torque of a three-phase induction motor
Explanation: Series test lamps (and related test-lamp methods) are traditional practical tools for checking supply presence and continuity/fault location in installation work. Precise resistance measurements need ohmmeters/meggers; motor torque is not set with a test lamp.
8Shop discipline in an electrical laboratory requires that metallic tool handles and uninsulated pliers should:
A.Always be preferred for live 230 V terminal work without isolation
B.Never be used on energised circuits; work only after isolation and verification
C.Be dipped in water before use to improve grip
D.Replace personal protective equipment for high-voltage substation entry
Explanation: Uninsulated or damaged tools must not be used on live equipment. Vocational safety practice is lock/isolate, verify dead, then work. Water worsens shock risk; PPE never replaces isolation discipline.
9Ohm’s law states that for a metallic conductor at constant temperature, the current I is:
A.Inversely proportional to voltage V and proportional to resistance R
B.Directly proportional to voltage V and inversely proportional to resistance R (I = V/R)
C.Equal to V × R in all cases including open circuits
D.Independent of both V and R
Explanation: Ohm’s law: V = IR, so I = V/R when temperature (and thus R for many conductors) is constant. Current rises with voltage and falls with resistance. This is a foundation unit in FA Electrical Wiring / current electricity.
10A resistor of 12 Ω carries a current of 2 A. The voltage across it is:
A.6 V
B.10 V
C.24 V
D.48 V
Explanation: From Ohm’s law, V = IR = 12 Ω × 2 A = 24 V.
