Answer / abhi
it is due to form factor....but
form factor = rms value / average value
for a sinusoidal supply of voltage in terms of sine wave
ff = a/root 2 (rms) / 2a/pie (avg)
= 1.11
and hence 11*1 = 11 kv
11*2 = 22 kv
11*12=132 kv and so on....
Is This Answer Correct ? | 10 Yes | 1 No |
because of form factor factor
form factor= average value of emf/rms value of emf
which is equal to 1.11
