General Engineering (Electrical) flashcards for SSC JE
20 of 51 cards from the General Engineering (Electrical) deck — real questions with worked answers.
State Ohm's Law and give its mathematical form.
At constant temperature, the current (I) through a conductor is directly proportional to the voltage (V) across it: V = I × R, where R is the resistance in ohms.
State Kirchhoff's Current Law (KCL).
The algebraic sum of all currents meeting at a node (junction) is zero; i.e., total current entering a junction equals total current leaving it. It is based on conservation of charge.
State Kirchhoff's Voltage Law (KVL).
The algebraic sum of all EMFs and voltage drops around any closed loop in a circuit is zero. It is based on conservation of energy.
What is the formula for resistance of a conductor in terms of its dimensions?
R = ρL/A, where ρ is resistivity (ohm-metre), L is length, and A is cross-sectional area.
Give the formulas for equivalent resistance of resistors in series and in parallel.
Series: R = R1 + R2 + R3 + ... Parallel: 1/R = 1/R1 + 1/R2 + 1/R3 + ... (for two resistors, R = R1R2/(R1+R2)).
Write the three forms of electrical power dissipated in a resistor.
P = VI = I²R = V²/R, measured in watts.
What is the magnetic reluctance of a magnetic circuit and its formula?
Reluctance (S) is the opposition offered to magnetic flux. S = l/(μ₀μᵣA), measured in ampere-turns per weber (AT/Wb). It is analogous to resistance in electric circuits.
State the magnetic circuit equation analogous to Ohm's law.
Flux (Φ) = MMF / Reluctance = (N·I)/S, where MMF is magnetomotive force (ampere-turns) and S is reluctance.
Define magnetomotive force (MMF) and its unit.
MMF is the driving force that establishes magnetic flux in a magnetic circuit; MMF = N × I (number of turns × current). Its unit is ampere-turns (AT).
Define magnetic flux density (B) and give its unit.
Flux density B = Φ/A, the flux per unit cross-sectional area. Unit: tesla (T) or weber per square metre (Wb/m²).
What distinguishes ferromagnetic, paramagnetic, and diamagnetic materials?
Ferromagnetic materials (iron, nickel, cobalt) have relative permeability >>1 and are strongly attracted; paramagnetic materials have μᵣ slightly >1 (weakly attracted); diamagnetic materials have μᵣ slightly <1 (weakly repelled).
What is the difference between hard and soft magnetic materials?
Soft magnetic materials (e.g., silicon steel) have a narrow hysteresis loop, low coercivity, and are easily magnetized/demagnetized—used in transformer/machine cores. Hard magnetic materials (e.g., alnico) have a wide loop and high retentivity—used for permanent magnets.
What is hysteresis loss and what does it depend on?
Hysteresis loss is the energy dissipated as heat due to repeated magnetization reversal of a core. By Steinmetz: Wh = η·Bmax^1.6·f·V, depending on maximum flux density, frequency, and material constant.
State Faraday's two laws of electromagnetic induction.
1st law: An EMF is induced in a conductor whenever the magnetic flux linking it changes. 2nd law: The magnitude of induced EMF equals the rate of change of flux linkage: e = -N(dΦ/dt).
State Lenz's law.
The direction of an induced EMF (and current) is always such that it opposes the change in flux that produced it. It accounts for the negative sign in Faraday's law and is a consequence of conservation of energy.
Differentiate statically and dynamically induced EMF.
Statically induced EMF is produced when flux changes through a stationary conductor (e.g., transformer EMF). Dynamically induced EMF is produced when a conductor moves through a magnetic field (e.g., generator EMF, e = Blv).
Define self-inductance and mutual inductance.
Self-inductance (L) is the property of a coil to oppose change in its own current by inducing an EMF (e = -L di/dt). Mutual inductance (M) is the EMF induced in one coil due to changing current in a neighbouring coil.
What is the RMS value of a sinusoidal AC quantity and its relation to peak value?
RMS (root-mean-square) value is the equivalent DC value producing the same heating. For a sinusoid, Vrms = Vmax/√2 = 0.707 Vmax.
Define form factor and peak factor for a sinusoidal waveform.
Form factor = RMS value / average value = 1.11 for a sine wave. Peak (crest) factor = maximum value / RMS value = √2 = 1.414 for a sine wave.
Define power factor and give its formula.
Power factor is the cosine of the phase angle between voltage and current: pf = cos φ = real power (P) / apparent power (S). It ranges from 0 to 1.
Planning General Engineering (Electrical) for SSC JE
General Engineering (Electrical) is about 21% of the SSC JE syllabus by topic count — 23 of 108 topics, spread over 11 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 15 hours.
The heaviest chapters are Generation, Transmission, and Distribution (3 topics), Basic Concepts (2 topics), Circuit Law (2 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
