Question { HCL, 38882 }

why earth hole size is biggest in plug point?


Answer

R = row L/A.......(1)
r is increase so the a is decrease so the depend to this
equation 1

Question { 5980 }

CAN ANYBODY EXPLAIN WHAT ACTUALLY MEAN BY THE PHASE
DEFFRENCE? R,L,C CIRCUITS?


Answer

Two oscillators that have the same frequency and different
phases have a phase difference, and the oscillators are said
to be out of phase with each other. The amount by which such
oscillators are out of step with each other can be expressed
in degrees from 0° to 360°, or in radians from 0 to 2π. If
the phase difference is 180 degrees (π radians), then the
two oscillators are said to be in anti phase IS CALLED PHASE
DIFFERENCE...
resistor, an inductor, and a capacitor,
connected in series or in parallel. The RLC part of the name
is due to those letters being the usual electrical symbols
for resistance, inductance and capacitance respectively. The
circuit forms a harmonic oscillator for current and will
resonate in just the same way as an LC circuit will. The
difference that the presence of the resistor makes is that
any oscillation induced in the circuit will die away over
time if it not kept going by a source. This effect of the
resistor is called damping.

Question { Bhel, 9313 }

Why current transformers are rated in BURDEN instead of VA?


Answer

bcz they are low rating so the BURDEN instead of VA... and VA depends in voltage and current
