An open causes resistance to decrease; a short causes resistance to increase.
Excessive current flow in an open circuit; no current flow in a shorted component.
No current flow in an open circuit; excessive current flow in a shorted component.
Minimum voltage development across the open component; maximum voltage development across the shorted component.
Magnetism
Reluctance
Direct current
Electromagnetic induction
Current is zero when voltage is zero; voltage is maximum when current is maximum.
Current is maximum when voltage is zero; voltage is maximum when current is zero.
If current decreases, voltage aids the decrease.
If current increases, voltage aids the increase.
