Punjab PSEB Matric NSQF Power study guide
Punjab PSEB Matric NSQF Power · Work through your exam, one topic at a time.
The Punjab School Education Board (PSEB) was set up by a legislative enactment in November 1969, and its Class 10 (Matriculation) examination is the board's main school-leaving assessment for Punjab. Within that examination, the NSQF vocational stream lets candidates offer a trade subject - here, Power - alongside their general subjects. This page is an independent study resource for candidates preparing the Power trade; it is not affiliated with, endorsed by, or operated by PSEB, and candidates should always treat pseb.ac.in as the authoritative source for notices, dates and syllabus. The paper is built on two halves. The trade theory half tests the electrical and power fundamentals behind the trade - supply, wiring, machines, protection, safety and measurement. The practical half tests whether you can actually perform the trade: tool handling, wiring jobs, testing, fault-finding and the workshop discipline expected of someone entering the power sector at entry level. Topics on this exam: NSQF Vocational Trade Theory (Power) and NSQF Vocational Practical / Skill Component. The Punjab PSEB Matric NSQF Power study guide has 2 sections and about 782 words.
01Vocational Trade Theory (Power)
The PSEB Matric NSQF Power trade theory paper checks whether you can explain the electrical principles behind power work and apply them to numbers and circuits. Expect questions on units, Ohm's law, AC/DC supply, protective devices, earthing, transformers, motors, and generation-to-distribution terms. Current (A), voltage (V) and resistance (Ω); Ohm's law V = IR. Power P = VI = I²R = V²/R.

The practical component tests safe workshop performance: using a multimeter, wiring a lamp and socket circuit, earthing, insulation testing, reading a motor nameplate, and locating simple faults. Marks are lost for unsafe sequencing even when the final circuit works. Select the correct function and range before touching probes. Voltage is measured in parallel; current in series; resistance with the circuit dead, isolated and discharged.

- Practice questionsIn a power distribution system, what is the standard function of a transformer?
- FlashcardsOhm's law. For a conductor at constant temperature, V = I × R.
- Cheat sheetOhm's law: V = I × R; power P = V × I = I²R = V²/R.
- Key termsElectric current. The rate at which electric charge flows past a point in a conductor, measured in amperes.
- Study planDefine the core electrical quantities (current, voltage, resistance, power, energy) and state their SI units and symbols without notes.
- Common mistakesClassroom numericals usually end at 'I = P/V', so candidates treat the calculation as the whole answer and never practise the second step of matching to standard current ratings or applying correction factors from the wiring tables.
