Answer Posted / anu
guess:In this case, the resistance becomes zero Ω as well,
increasing total current to a value of infinity(i=v/r).no
real voltage source could arbitrarily supply a huge
overload current and maintain steady voltage at the same
time.this huge current results in the generation of heat
and sparks
