Can a small 12 volt 200 watt electric motor run safely off a deep cycle battery whilst the battery is being charged at say at 20 amperes?
Should be OK. If the motor draw is 200 watts, and the charge current is 20 amps, you've got (12 x 20) = 240 watts in and only 200 out. The battery will charge at a rate of (40/12) about 3.3 amps, so be aware that (i) the battery will take longer to charge than if the motor wasn't running, and (ii) once you stop the motor, the charge current is the whole 20 amps and you'd need to be sure that the battery won't overcharge.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
How is Alessandro volta's name linked to electricity?
He invented the battery and and the term volt was named after him.
Who is alessandro volt?
Alessandro Volta was the man who created the first battery known as the voltaic pile. :)
How long will it take a 13 watt solar panel to charge a 12 volt battery?
The time it takes to charge a 12-volt battery with a 13-watt solar panel will depend on various factors such as the battery's capacity, its current state of charge, weather conditions, and efficiency of the charging system. On average, it may take around 8-10 hours of good sunlight to fully charge a depleted 12-volt battery with a 13-watt solar panel.
Can a 12v solar panel charge a 12v battery?
If the 12 volt solar panel output voltage is always higher than the 6.5 watt battery voltage. To charge a battery, a voltage greater than the battery must be applied to the battery, otherwise the battery will try to charge the charger.
What size of panel needed to charge a 12 v 35 amp battery for 13 hours?
What is the Solar panel wattage to use charging a 12 volt 45 amp battery.
How many 290 lumen 7 watt light bulb is needed to power a 5 watt 12 volt solar panel?
None, since one does not normally "power" a solar panel. However a single 7w lamp would be useable with a 5watt panel but with reduced efficiency unless the panel was used to charge a battery first and then the bulb was powered by the battery.
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.
How do you recharge a 12 volt battery using solar power?
To recharge a battery you put the solar panel in the light and hook the red cable on the positive and the black on the negative
How much time to charge a 12 volt battery with 35watt solar panel?
A very, very, long time. Only a guess but I would venture to say at least 15 hours.
If you have a 123 Watt 7 amp solar panel working on charging a 12 volt 225 amp hour gel battery how long will it take the solar panel to charge the gel batter?
You need to provide many more details. So assuming that the panel voltage is reasonable, the panel is clean, it is sunny and the panel is pointed at the sun. Then it will take about 225/7 hours to charge the battery. About 300 hrs. But in fact charging is only about 85% efficient (charge at 14 V get energy out at 12V or so). This ups the charge time to maybe 350 hrs or so. Charging can be improved by inserting a MPPT charger between the battery and the panel. This bit of electronics decouples the battery voltage and the panel voltage allowing the panel to be operated at its' most efficient voltage. That might knock off 15% of charge time bringing you back to 300 sunny hours.
Can you use a 12 volt battery to charge a 48 volt battery?
No
Can you charge an 8 volt battery with 6 volt charger?
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
