Q1. In parallel combination of resistance, the voltage is _________.
(a) lower across largest resistance
(b) higher across largest resistance
(c) same across each resistance
(d) higher across smaller resistance
Q2. Electrical conductivity of a conductor is measure in __________.
Q3. A D.C. Generator has 6 poles, A brush shift of 6° actual means a brush shift of
(a) 6° electrical
(b) 18° electrical
(c) 30° electrical
(d) 2° electrical
Q4. Full-load terminal voltage in an over-compounded generator with respect to no-load terminal voltage is–
Q5. Total number of poles and slots in a DC machine are 4 and 8 respectively. Angular slot pitch is ……….
(a) 45 electrical degrees
(b) 90 electrical degrees
(c) 135 electrical degrees
(d) 180 electrical degrees
Q6. Which is the most severe fault?
(a) phase to phase fault
(b) phase to earth fault
(c) Three phases to ground fault
(d) Phase to phase to earth fault
Sol. In parallel combination of resistance, the voltage is same across each resistance.
Sol. The electric conductivity is the measure the ability of a conductor to conduct electricity.
The conductivity formula is the inverse of the resistivity that is:
σ = refers to the electrical conductivity
ρ = refers to the resistivity
The conductivity unit is Siemens per meter.
Sol. (θele= P/2×θmech )
= 18° electrical
so, for over compound full load terminal voltage will be more than NoA-load voltage.
Sol. Slots per pole =8/4=2
Angular slot pitch = (180°)/(slots per pole )
Sol. LLLG or three – phase to ground fault is most severe and in this short-circuit current value is maximum.
Severity of fault.
LLLG > LLL > LLG > LL > LG
