Can a 0.9V 400MA solar panel be used to charge 2 AA batteries?
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
How is a voltmeter wired in with the load?
An inline volt meter is designed to have the voltage pass through it. The wire has to be cut or otherwise disconnected, and the meter installed between the disconnected ends of the wiring.
How would the bulbs shine in a series circiut?
An electric light bulb, incandescant type, is designed to operate at a certain voltage. Let's take 12 volt car headlights for example. Two 12 volt lights are connected in parallel in a car to provide the headlights, the same 2 lights could be connected in series if used on a truck with a 24 volt battery, or 20 of the lights could be connected in series if connected to a 240volt home electric circuit. (In the US think of 10 connected in series on your 110 volt system.) The lights would each produce about the same light output, but the number of lights would cause more light in total. In series there is a problem, when one light failsm they all go out. That's why lights in a house are connected in parallel.
What is the voltage when batteries are connected in parallel?
When placing voltage sources in parallel, the total voltage is the same as the individual battery's voltages. For example: If I was to place 4 "AA" 1.5 volt batteries in parallel with a life of x hours, the out put would be 1.5 volts with a life of 4x hours. note: never place batteries in parallel that are not in the same condition (charge, voltage, ect...).
Can you start a two six volt battery tractor with one 12 volt battery?
It depends on how the two six volt batteries are connected. If they are in parallel then the answer is no. If they are connected in series then the answer is yes. To find out for sure check the voltage that the starter needs. If it says 12 VDC then you will know that the two six volt batteries are wires in series and can be replaced with a 12 VDC battery.
If Four 12 voltsbatteries connected in parallel and one 12 volt battery in series how much voltage is active across circuit?
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
How do you connect volt meter in battery charger?
To measure voltage be in parallel with the battery. Series would measure current. Parallel measures potential.
Four 9-volt batteries are connected in parallel how much voltage is active?
the answer is 36 volts
How much voltage is active when four 9 volt batteries are connected in parallel?
9 volts
How do you connect 2 6 volt batteries in parallel to make 12 volts?
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.
Can 6 volt batteries connected in series be jump started with a 12 volt battery?
Two 6 volt batteries in series, yes. In parallel, no.
How do you connect a volt meter to a car?
It depends on what you want to monitor. Most commonly the volt meter is connected in parallel with the battery or the alternator.
What is the total voltage if 12v 6v and 2.5v batteries are connected in parallel?
Don't try it in real life -- the batteries will become extremely hot and catch fire. Theoretically, the circuit is not allowed -- fundamentally impossible. Each battery can be thought of as a voltage source in series with a variable resistance (the internal resistance of the battery). If you connect these in parallel, the 12 volt battery will attempt to bring the parallel voltage up to 12 volts. To do so, it will push current out to the other two batteries. The other two batteries will supply their respective voltage to try to counteract this. They will begin to heat up; As the 12 volt battery supplies current above what it is designed to provide, its' internal resistance will increase, causing an increased voltage drop inside the battery (causing more heating in the 12 volt battery), which causes the 12 volts it is trying to push out to drop to closer to the other batteries voltages. the 2.5 and 6 volt batteries' internal resistances will also increase as they accept the current from the 12 volt battery, allowing the parallel voltage to increase to closer to what the 12 volt battery wants. This will continue until only one battery survives, most likely.
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.
