In order to reduce the stroboscopic effect, we are normally
using the twin lamp fittings in the factories...

Answer / ramadass - loop mobile, mumbai

Normally lights gets ON & OFF as sine wave cycle (peak or
Zero) respectively. In case of two TL fiiting, we have to
use a Capacitor in series on One TL circuit & 2nd ckt to be
as usual.
Now 1st TL is ON & another is OFF and next time 1st TL is
OFF & 2nd is ON, so that we can see the rotating parts
(motor etc) without break.

Electricty is generated at around 16kV, then step up to 220kV for transmission then steped down to power transformers then DTs and then through the LT n/w it reaches the consumer end. At the consumer end 230V supply is required. So, why is electricity not generated directly at 230V and transmitted?

An impedance of 100 ohms resistance and an unknown inductance is connected across the capacitor. The resulting impedance is a pure resistance of 500 ohms ifω = 10^5 rad/sec. calculate the values of inductor and capacitor.
