Current flows from negative to positive. The current flows because of OHM's law. Click the link.

When the flashlight is on is it static or current electricity?
When the flashlight is ON , electrical current is flowing from one terminal of thebattery, through the light-bulb filament, to the other terminal of the battery.
How does emergency light switch work?
An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off. One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation. note: The normally off is not use. And may be use for some purpose.
Where do the electrons go when you discharge them?
In order to make a current flow, there's always a source of power. It may be a battery or some other"power supply". For every electron that comes out of one terminal of the power supply, an electrongoes into the other terminal.
Why do the terminals of the battery have to be connected to different poles of the light bulb for the circuit to complete in a safe manner?
The current flows from the positive terminal, along the wire, through the bulb and along the other wire back to the negative terminal.
What describes electricity flowing from a battery though a switch to a light bulb?
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
How do you hook up a dc amp meter?
You disconnect your negative (-) battery terminal and connect one of the meter's probes to the (-) battery cable and the other terminal to the (-) battery post. Set your multimeter to mA/A and select DC.
What happens to a current as it through a circuit?
The current flowing out of one terminal of the power supply ... like a battery ... must all eventually arrive at the other terminal of the power supply. If there's only a single path between the power supply terminals, then the current is exactly the same at every point around the path. But it doesn't matter how large the circuit is, how many components there are, or how many ways there may be for the current to split up and recombine on its way around. For every electron that leaves one side of the battery, an electron returns to the other side ... exhausted and completely out of energy.
What are the two electrodes of a battery called?

How do you hook a car fan to the battery to see if it works?
If you have the fan removed from the car, you can just quickly use jumpers to connect the negative terminal of the fan to the negative terminal of the battery, then connect another jumper to the positive terminal of the fan,and with insulated hands(!) touch the other end to the positive terminal of the battery. If the fan runs, it's fine.
What do you say is wrong with you to get Dilaudid?
Intractable pain usually related to terminal cancer or other Terminal disease that causes PAIN.
How do you jump start a vauxhall vivaro van?
To jump start a Vauxhall Vivaro van, start by removing the battery cover. Taking your cables, connect one end of the lead to the positive terminal on the discharged battery, then connect the other end of this lead to the positive terminal on the battery you are jumping from. Take the other lead and connect it to the negative terminal on the discharged battery. Next, use the end of this lead to connect somewhere to ground the current; for example, the engine block or screw connection in the engine suspension on the vehicle providing the jump. When finished, remove the leads in the exact opposite direction you applied them.
Would AC or DC be better to use when charging a mobile phone to make a call?
Answer: DC. Explanation: A mobile phone is powered by a battery. A battery stores electric charge. When wires connect the two terminals ['+' terminal and '-' terminal], then a current will flow through the wire from the '+' terminal to the '-' terminal. The electric circuits that operate the cell phone (and any other electronic device) require electric current to operate. In order to store electric charge in the battery you must apply DC current to the battery. AC means 'alternating current', which means that half the time the current flows in one direction along the wire that carries the AC, while the current flows in the opposite direction the other half of the time. One cycle of the AC is the total time for the current to flow in both directions. If you tried to charge a battery with AC, during each half of the cycle the current would undo the charging that the previous half-cycle had provided. There are devices that can convert AC into DC. (They are called converters, or rectifiers.) For a device like a cell phone you would plug the converter into the AC electric outlet, and the converter would produce DC coming out of a cable which you would plug into your cell phone to charge the battery. The converter is a relatively simple electronic circuit. If you want to know more about it, then ask. 25August,2008
