Assemble a small regulated supply around a three-terminal regulator and verify the output voltage against the datasheet tolerance.

List the workshop consumables, hand tools and PPE needed for a one-person repair bench and cost each item at local market rates.

Draw and explain the operating point of a BJT in common-emitter configuration, and calculate bias resistors for a specified quiescent current.

Compare the characteristics and typical applications of a PN junction diode, Zener diode, LED and photodiode in a written table.

Construct and verify a transistor switching circuit driving a relay, including the freewheeling diode, and measure base current versus collector current.

Convert between binary, decimal and hexadecimal and perform two's-complement subtraction on at least 10 examples.

Simplify Boolean expressions using truth tables and Karnaugh maps, then verify each simplification with a logic-gate circuit or simulation.

Measure voltage, current and resistance with a digital multimeter, explaining why current measurement needs a series connection and the correct jack.

Use an oscilloscope to display and measure amplitude, period, frequency and phase of two signals, and state the effect of probe attenuation setting.

Verify the truth tables of AND, OR, NOT, NAND and XOR gates using a logic probe or LEDs and record the results.

Test a diode, transistor and electrolytic capacitor with a multimeter in both forward and reverse bias and interpret each reading.

Describe the purpose of a function generator, a regulated bench supply and a clamp meter, and state one misuse that damages each instrument.

Trace the fault in a non-working electric iron, mixer grinder or table fan using a systematic supply-to-load voltage check, and record each test point reading.

Test and replace a heating element, a triac speed controller and a motor-run capacitor, confirming the repair with a load test.

Explain the function and failure symptoms of a thermostat, thermal fuse, bimetallic cut-out and overheat protector in household heating appliances.

Interpret the wiring and safety requirements for earthing, MCB rating and cable gauge in a domestic appliance circuit.

Dismantle, clean, lubricate and reassemble a small appliance, then verify insulation resistance and earth continuity before returning it to the customer.

Explain AM and FM modulation, bandwidth and the role of the tuner, IF stage and detector in a radio receiver block diagram.

Set up and align a simple audio amplifier, measuring gain, frequency response at three points and total harmonic distortion by ear or meter.

Diagnose a no-picture or no-sound fault in a television or set-top box by checking supply rails, signal cable and connector continuity in order.

Describe the signal chain from microphone to speaker in a PA system and identify causes of hum, feedback and channel imbalance.

Compare composite, component and HDMI connections by signal type, resolution support and common failure symptoms.

Write, compile and upload a program that reads a digital sensor and drives an LED and relay output on a microcontroller board.

Interface an analog sensor such as an LDR or thermistor, convert the reading, and apply a threshold to switch a load automatically.

Explain the difference between a digital and analog sensor signal and state when signal conditioning or a pull-up resistor is needed.

Apply lockout-tagout, correct fuse and MCB selection, and safe discharge of capacitors before servicing a live-capable circuit.

Demonstrate the correct procedure for earth-continuity and insulation-resistance testing and state the pass criteria you would apply.

Prepare a customer-facing quotation for a repair job that separates parts, labour and tax, and state the warranty terms in writing.

Draft a simple invoice and a job card that records complaint, diagnosis, parts used, charges and customer sign-off.

Answer behavioural and technical interview questions aloud, including how you explain a fault and a repair cost to a non-technical customer.

Complete two timed mixed-domain mock tests and review every wrong answer to its underlying concept.

List the licences, GST registration and electrical-contractor requirements that apply to a small service business in Maharashtra and note where to verify each.
