Ohm’s Law A law that states that the current in a circuit is directly
proportional to the voltage and inversely proportional to the
resistance.
I =
E
R
E = Electromotive Force (Voltage) in Volts
R = Resistance in Ohms
I = Current in Amperes (Amps)
Open Drip Proof (ODP) A motor enclosure type that permits air flow through the motor,
but is designed to prevent liquids or solids falling from above
at angles up to 15 degrees from the vertical from entering the
motor.
Open-Loop Control A control technique that does not use a feedback signal.

Overcurrent A current in excess of the rated current for a device or
conductor. An overcurrent can result from an overload, short
circuit, or ground fault.
Overload Can refer to an operating condition in excess of the full-load
rating or a current high enough to cause damage if it is present
long enough. Short circuits and ground faults are not overloads.
Overload Relay A device used to protect a motor from damage resulting from an
overload.
