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.
The light bulb must be connected in a closed circuit with a power source, such as a battery or electrical outlet, for it to light up. This means that the positive terminal of the power source must be connected to the positive terminal of the light bulb, and the negative terminal of the power source must be connected to the negative terminal of the light bulb. This allows the flow of electricity to power the light bulb and make it light up.
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.
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.
A simple series circuit is typically used in a battery-operated torch. This circuit allows for the flow of current from the battery through the light bulb, providing illumination. The components are connected in a loop, where the positive terminal of the battery is connected to the light bulb and then back to the negative terminal of the battery.
Nothing, glass is an insulator.
The current flows from the positive terminal, along the wire, through the bulb and along the other wire back to the negative terminal.
If it is a 1.5 volt bulb you can connect it through a series circuit directly to your battery. If the bulb is not made to run on 1.5 volts and needs another voltage, it may not light up!
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.
The switch is not needed.
Draw a battery and light bulb. Draw a line from the smaller connector on the battery to the bottom of the light bulb, this is positive on both. Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both. Looked all over and can't seem to find this one.
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.
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.
