What else can I help you with?
Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?
No, the charging voltage needs to closely match the battery or BOOM!
Why can't you use a multitester as an ohmmeter if it has no battery?
The battery is used by the meter to apply a voltage across the resistance being measured and determine the current which determines the resistance. If there is no battery it can't supply the voltage and can't measure current, so no reading.
883 battery voltage?
This is not a question. You should repost with more detail so someone can help. An 883 has a 12 volt system and a 12 volt battery. It should charge to around 12.5 to 13 volts. If you apply a load test, it should not drop more than one volt. Hope this helps.
How do you find a shorted wire current draw with the key in the off position if you know which main fuse is involved on a 94 S-10 Blazer?
You need to do a parasitic draw test. Use a voltmeter to check base voltage of battery. Then crank the engine, check voltage at battery. It needs to be at least two more volts than previous base voltage. Then apply a load or turn on headlights. The voltage should not drop over one volt. Ideal base voltage at battery terminals is 12.6, ideal charging voltage would be 14.6, ideal loaded voltage would be 13.6 volts aproximately. If you find a drainage in system and you have a good battery, then you need to check radio and main accessories first, then check door latch switches and courtesy dome lamps.

How many amps do you need to charge a 7.2 battery?
Hi, To properly charge a battery, you should apply a voltage that causes current to flow (being careful to get the plus and minus hooked up properly!) at about 1/10th the amp/hour rating of the battery. For a 7.2 amp/hour battery you should not charge much faster than 0.72 amps. This is the best practice to prolong the life of your battery. Chris
Should a battery charger have to have a transformer and a rectifier to produce DC volts?
Yes, a battery charger typically requires both a transformer and a rectifier to convert AC voltage from the power source into the DC voltage needed to charge batteries. The transformer steps down the voltage to a suitable level, while the rectifier converts the AC voltage to DC. Some modern chargers may use switch-mode designs that incorporate these functions in a more compact form, but the principles of voltage transformation and rectification still apply.
What is the significance of piv of diode?
The PIV (Peak Inverse Voltage) rating of a diode is the maximum voltage that you should apply to it in the reverse biased condition. Exceeding this voltage can destroy the diode.
How do you wire two 12 V batteries to get 24 V?
You would wire them in series. This means: Connect one battery's positive pole directly to the other battery's negative pole. Use the other two unused battery poles (one positive and one negative) to apply voltage to your circuit. The applied voltage will be 24 volts.
Does the voltage output increase when a generator is made to spin faster?
You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.
How do you know when alternator is not working?
The easiest way to check is apply a volt meter to the battery terminals. With the engine off the voltage should read around 12 volts. With the engine running there should be an increase in the voltage to around 14 volts. If the voltage reading stays at or decreases from the engine off level then the alternator is probably not working. I would then remove the alternator and take it to an auto parts store and have it bench tested to check it for proper operation.
What is impresses voltage?
It is another way of saying "Apply a voltage" or "supply (something) with a voltage"
What do the warning lights on your Toyota indicate?
Typically if both the battery and brake warning lights are on it means your alternator is not producing a proper amount of voltage for continuous charging to your battery. The proper way to find this out would be to apply a meter tester to your battery and run your vehicle at idle. The meter should be set on a voltage setting between 12~16v DC. On idle the alternator should produce at minimum 14.2 volts. If it is not, then therein lies your problem. 99% of the time owners will replace the battery first, but in most cases it is not necessary. Only if you have driven the vehicle continuously while alternator is failing will it become necessary to also replace the battery, as it will end up burning up the battery from continuous draining and recharging.
