current drain การใช้

• NiMH cells are advantageous for high current drain applications, largely due to their lower internal resistance.
• Other tests, usually involving current drain, are used to determine the residual charge capacity of a battery.
• The car battery would discharge, and the car alternator would be overloaded, if this current drain were sustained.
• If not, then you only need to know where the current drains are, not where the sewers run.
• Not only do you have the start up current drain but the manufacture expects you to add other hardware at some time.
• Other factors affecting device longevity include programmed output and algorithms ( features ) causing a higher level of current drain from the battery.
• The current drain from this battery was only 4 mA, Such battery consumption rate still made the TR-1 rather expensive to run.
• It was found that it had been left on by accident, leading to a current drain on the batteries that overheated them until they burst.
• Other types simply include a 1.5 V battery in the microphone housing, which is often left permanently connected as the current drain is usually very small.
• :The " super heavy duty " cells are zinc chloride battery and they are near useless at high current drains, which would include walkie-talkies in transmit mode.
• A rare form of " C " battery was the " bias cell ", a button-size miniature battery designed to deliver a constant voltage with no current drain.
• It is usual for such systems to include a backup battery, either disposable in a holder ( current drain is extremely low and life is long ) or soldered-in rechargeable.
• Button cells have a limited current drain; for example an IEC PR44 cell has a capacity of 600 milliamp-hours ( mAh ) but a maximum current of only 22 milliamps ( mA ).
• These are most commonly used in portable devices that have low current drain, are used only intermittently, or are used well away from an alternative power source, such as in alarm and communication circuits where other electric power is only intermittently available.
• :If you make logic gates out of transistors without matching all the impedances and current drains for the entire analog states encountered in operation, something with 5 gates might work fine, but extending it to 6 gates might suddenly fail with no obvious reason.
• Generally ( but not always ), user-accessible ports on a computer are pretty well protected against excessive current drain, short circuits, improperly applied power and other common problems, simply to avoid accidental damage to internal components due to a failure in a peripheral .
