What else can I help you with?
What device shows the amount of energy a battery is producing?
That would have to be a 'wattmeter', but they're seldom available. In terms of more readily available instruments, you'd need to use a voltmeter, reading the battery's voltage, and an ammeter inserted in series in one of the battery's connections, reading the current from the battery. The rate at which the battery is supplying energy at any moment is then the product of the two meter readings.
Why must there be two connections to a batter and to a light bulb?
The electrons must go from the battery to the light-bulb, then come back again to the battery through the other connection. If there is only one connection, there will soon (within microseconds or so) be an accumulation of electrons that will repel any additional electrons - the current will stop flowing.
What is star and delta in electrics?
They are two of several standard connections for three-phase alternating current machines.
What is the behavior of current and voltage in a series cricuit?
Kirchhoff's Current Law: The sum of the signed currents entering a node is zero. A consequence of this is that, in a series circuit every node only has two connections, one entering and one leaving, thus, in a series circuit, the current is the same at every point. Kirchhoff's Voltage Law: The sum of the signed voltage rises going around a series circuit is zero. This means, for example, that if you have two voltage drops, such as two bulbs in series with a battery, the voltage drops across them will add up to the voltage across the battery.
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
Why current gets divided in parallel combination but not in series combination?
Current travels in loops. In series you have one loop, or path for current to take. With parallel connections, there's at least two. This is why current divides in parallel and not in series.
What uses chemical reactions to create an electrical current?
A battery uses chemical reactions to create an electrical current. This occurs through the movement of ions between two electrodes (anode and cathode) in the battery, generating a flow of electrons that can be used as electrical power.
How do you convert chemical energy in a battery to electrical energy?
Chemical energy in a battery is converted to electrical energy through a chemical reaction that occurs within the battery. The reaction causes a flow of electrons between the battery's two terminals, generating an electric current. This current can then be used to power electronic devices.
Why might a 1984 Nissan Quest battery be discharging if not driven for two or more days in the winter?
You might have loose connections or low cells on your battery. Check the cells on the battery and if they are low fill them with distilled water only. Also make sure your alternator is giving the battery a good charge.
The voltage or current capacity of a battery can be increased if two or more cells are connected together To increase current capacity a series connection is used?
Each cell of a battery has a predefined voltage, and for a given type of battery, a predefined maximum current capability. Putting cells in series, just like putting batteries in series, increases the voltage (1 AAA battery = 1.5 volts, 2 AAA batteries in series = 3 volts). Putting cells in parallel increases the amount of current that can be drawn from them (1 cell = 1 cell max. current, 2 cells in parallel = 2 cells worth max current). Note available power will be the same (P = V*I), so whether you use a series or parallel connection usually depends upon the desired output voltage.
What type of energy does a battery produce?
A battery produces electrical energy through a chemical reaction that occurs between its two terminals. This chemical reaction releases electrons, which flow through a circuit, creating a current of electricity.
Why does batteries have direct current?
In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). current (AC). According to Wikipedia http://en.wikipedia.org/wiki/Direct_current A battery has two terminals- a positive and a negative.When a battery is in use, current flows from the positive terminal of the battery around the circuit back to the negative terminal in one direction. according to http://www.teachnet.ie/torourke/basics.htm
