Q9: Part c all ::)
Ghost Of Highbury:
The voltage drop. Refer to the nov 09 Q.
The overall voltage reduced from 22K Volts due to the resistance of the wire, till it reaches the receiving end.
I know this is confusing sh*t, it had appeared in my paper! nov 09! V = 2.5*3 = 7.5
from wiki "For example, an electric space heater may very well have a resistance of ten ohms, and the wires which supply it may have a resistance of 0.2 ohms, about 2% of the total circuit resistance. This means that 2% of the supplied voltage is actually being lost by the wire itself."
