when the aircraft is in the air, to protect the plane from
a lightning strike, aircraft earthing is done.
the whole of the outer body is made up of a good conducror
of electricity(alluminium) and this outer body is insulated
from the other parts of the plane. when the lightning
strikes, the whole body of the plane acts as a conductor
and the lightning continues even after the length of the
plane and also may reach the earth. The inner surface of
the plane and thus the passengers are not affected by the
strike

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?

HOW TO CALLICULATE RESITENCE,REACTANCE AND IMPEDENCE VOLTGE OF TRANSFORMER 13.33 KVA 144/240 VOLTS 93/56 A WITH FORMULA
In 11/0.414 KV Parralel supply network with Bus tie closed what will be the fault level is it doubled or halved??
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
