What is dispersion of light? What is its cause?

Answer»

Solution :`N_P=100` Transformer ration K = 100
(a) Number of TURNS in secondary COIL
`N_S=N_PxxK=100xx100 = 10000`
(b) Input power `(P_p)` = Input voltage `(V_P)XX` CURRENT in primary `(I_P)`
`1100 = 220xxI_PimpliesI_P=5A`
(c) `V_S/V_P=N_S/N_P = ("Output Voltage")/("Input Voltage")`
`implies V_S=5/I_SxxV_P=KxxV_P`
`=220xx100 = 22000 V`

(d) `("Input Current")/("Output Current ")=I_P/I_S=N_S/N_P`
` implies 5/I_S = 100 " or " I_S=0.05A`
(e) For an ideal transformer,
Power in secondary = Power in primary
`impliesPs = 1100W`
