The quantity of current depends upon the load. Larger the
load, lesser will be current drawn on constant supply.
REMEMBER the Simplest formula of Electrical Engineering i.e.
OHM's LAW V=I*R
in given question V(=320 or 415V) is fixed. Now larger the
load small will be current and Vice Versa Lesser the load
Larger will be current drawn.

The highest current (in Amperes) can be equal to System
Voltage (in Volts) when there is no load (short circuit to
be precise) Hence current is too high and spark is produced.

7. A resistance of 30 ohm is connected across 240v supply. If a resistance R ohm is connected in parallel with 30ohm resistor across the same supply, the current drawn becomes triple of original one The unknown resistor R is
