What will happen if one battery terminal is connected to a light bulb?

Nothing will happen. It requires two wires to complete the circuit. Electrical current travels from the battery terminal through the wire to a metal portion of the base of the lightbulb. The current then travels up through the filament wire which glows as the current travels through. The current then travels back down the other side of the filament wire to the base of the bulb and thus through the second wire back to source, which is 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.
What will happen if a glass of a light bulb is connected to a battery?
Nothing, glass is an insulator.
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.
How can you use a wire battery and a light bulb to test an item to see if it is a conductor of electricity?
I am going to assume you meant Three wires, Battery and Light Bulb. (punctuation and plurals are important) Hook the light to one post of the battery Hooked from the light to the item being tested (use the other light connection, not the one connected to the battery) connect the other end of the test item to the unused terminal on the battery. Light comes on means it conducts electricity No Light, it does not.
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.
What would not be needed in the conducting loop in order to light a bulb - a positive terminal of battery - a switch - a negative terminal of battery - or a bulb?
The switch is not needed.
What wire goes to the f on the alternator?
If this connection is used, it is generally connected to the light in the dash that shows alternator fault (NOT the voltage gauge!) and then through the ignition switch to the positive battery terminal.
How do you hook up a switch to a light using a marine battery?
Hey. Same as any battery. Connect the Negative terminal straight to the Negative on the light (if needed), Normally the outer rim of the globe. Connect the positive terminal to the switch, then from the other plug on the switch to the positive terminal to the light. Done.
Why the bulb is not lighting when one wire or terminal is not connected?
When one wire or terminal is not connected to a light bulb, it is not possible for electricity to complete the circuit. When a circuit is not completed, the bulb will not light. An off switch, for example, breaks the circuit.
What does the four pin plug on the alternator of a 1991 Pontiac le mans do?
The 91 LeMans has a Delco CS121 alternator. The four pins (labeled P-L-F-S) function as follows. The P terminal is connected to the stator and can generates a half-rectified voltage when the alternator is operating. The L pin is connected to the battery Light on the dash board to illuminate the indicator if the alternator is not charging the battery. The F terminal is connected to the field and can be used to drive a tachometer. The S terminal is for the remote sense. If connected, the alternator will put out whatever voltage at the terminal is needed to give 14.5 volts at wherever the end of the sense wire is connected to the wiring harness (useful where there are a lot of loads and/or voltage sensitive accessories).
Chevrolet Sprint or Suzuki 86-89 Nippon Denso alternator-which terminal of the three flat blade terminals should be connected to the ignition circuit to tell the alternator to charge?
On most ND three pin plug style alternators the pins are marked as "L" / "S" / "IG" The only other connection is usually a large single post terminal marked "B" This is the main wire connected to your battery and is hot at all times. The three others are fairly easy to understand. "IG" This is the Ignition wire and issues the "wake up" to energise the circuit when ignition is switched on "L" This terminal is connected through to the charge warning light on your instrument cluster "S" This terminal is connected to your battery source and is hot at all times, it may even be connected to the main wire on the large B terminal in the loom but more often to the battery through a fusible link hope this helps
What are everyday uses of series circuits?
Your battery-powered flashlight is a good example of a DC series circuit. Battery power is DC. The battery is connected to a wire or piece of metal that's connected to a switch that is connected to an incandescent light bulb (resistor/thermistor) which is then connected to another piece of metal or wire which is connected to usually a spring in the end of the flashlight which creates a ground to the negative terminal of the battery.
