If you do smoke frequently, expect to test positive on a marijuana drug screen for anywhere from 3 weeks to almost 2 months. If you smoke everyday or several times a day, you can test positive for 2 months or more. Detection times also vary depending upon your weight, metabolism, and other person factors.
Definition: A transducer is a device that converts one form of energy â typically a signal â into another. Example: A speaker is a type of transducer that converts electrical energy (the audio signal) into mechanical energy (vibration of the speaker cone/diaphragm).
Efficiency is an important consideration in any transducer. Transducer efficiency is defined as the ratio of the power output in the desired form to the total power input. No transducer is 100 percent efficient; some power is always lost in the conversion process. Usually this loss is manifested in the form of heat.
