A circuit element with almost zero resistance is called a short circuit

Voltage in a short circuit is zero

Ideally, any current may flow through a short circuit

v=ri=0

 

 

A circuit element with infinite resistance is called an open circuit

Current in an open circuit is zero

Ideally, any voltage may drop across an open circuit

i=lim r->infty v/R=0
