what happen if we supply 220v dc suppy to the bulb or tube

Answer / nishant2110
Bulb : bulb will glow as usual. Since 220v of ac is rms
value. 220v of dc will produce same resistive effect
(heat) as was produced by 220v ac.
Tube : Tube will get damaged since DC won't be able to serve
the purpose of choke coil, choke coil works with ac
only. No back emf will generate to reduce the voltage
across tube

Answer / hareesh
WHEN DC IS GIVEN TO BULB IT WILL GLOW VERY HIGH AS COMPARE WITH WHEN DC IS GIVEN FOR SAME 220V. BECAUSE BULB AS RESISTIVE LOAD POWER CONSUMTION DEPENDS UPON RMS VALUE OF VOLTAGE AND CURRENT.

What is the disadventage of gland earthing(power cable) if any. ?
What do you mean by power transformer?
Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
