What is the difference between short to Battery and Open Load?
Related to a battery and open load is the battery just sitting there without anything connected. A short is a very low resistance attached to the tow terminals of the battery. For example, a wire connected across the battery terminals would constitute a short.
Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
How do you test speaker impedance?
You can measure speaker impedance with a multimeter set to the ohmmeter setting. Just place the multimeter probes across the two terminals of the speaker and you'll get the impedance value.
Can a 12-volt solar battery charger charge a 36-volt battery?
No, a 12-volt charger cannot charge a 36-volt battery. The electrical potential difference across the leads of a charger must exceed the electrical potential difference across the terminals of any battery it is expected to charge. And 12 volts is much less than 36 volts.WHY?The 36-volt battery would require at least 39.3 volts to get to a float charge. This would charge the battery to 80% quickly, and then take a logarithmic period of time to finish the battery. To actually charge the 36-volt battery correctly would require roughly 43.2 volts, but if we can't get 39, this is irrelevant.The 12-volt charger has no chance.The answer above is correct; there is no way the 12-volt charger can charge a 36-volt battery. However, the voltages given apply only to lead-acid batteries. They would be different for nickel metal hydride or lithium cells. You still need a charger with more voltage that the battery voltage in any case.
What about a cell's resting membrane potential is FALSE?
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
What is maintained across the terminals of a battery?
Current
What is the potential difference across the terminals of a battery?
Please share your answer?
Could a wire connected across a battery's terminals produce a current?
sure whatever?
An auto mechanic mistakenly drops a wrench across the two terminals of a car battery this causes?
A spark, a ruined battery and possible an exploding battery.
Why it's important to remove all jewelry before working around battery?
Jewelry is usually made of highly conductive metals and could easily short across the battery terminals if the jewelry comes into contact with them.
How do you Reset service lamp?
The easiest way to reset a service lamp on any vehicle is to disconnect both battery terminals first. Run a wire across both battery terminals and leave attached for at least a couple of hours. Detach the wire and reconnect the battery terminals. Your service light should now be out. Make sure that you do not run the wire across the positive and negative terminals of the battery. Make sure you disconnect both terminals and run the wire across the cables and not the actual battery terminals. If your service engine light is on it means your computer is registering a code. Make sure you take your car to have it diagnosed properly instead of resetting the light. It may be a serious code that could cause problems in the future.
When an auto mechanic drops a wrench across the two terminals of a car battery what happens?
A dead short occurs which can result in the battery exploding A completion in the external circuit of the battery
Why is it important to remove jewelry when working around forklift batteries?
Jewelry is usually made of highly conductive metals and could easily short across the battery terminals if the jewelry comes into contact with them.
How is the potential difference maintained across the end of the conductor?
That's the job of the battery or other power supply.
Why it is important to remove all jewelry before working around batteries?
Jewelry is usually made of highly conductive metals and could easily short across the battery terminals if the jewelry comes into contact with them.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
What will happen to the electric pressure differences across the battery terminals when a second long bulb is added in parallel to a single long bulb connected to a fresh battery?
there will be little or no change
