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 increases
