Word forms: (regular plural) open circuits
( Electrical engineering : Circuits , Electrical power , Computing and control )
If you were to use a voltage meter, you would find zero volts after an open circuit.
If the voltage is more than 60 percent of its open circuit voltage rating, the system will be affected by the capacitive current.
An open circuit is a circuit element that has an impedance approaching zero.
