Garden bulbs do not have to terminals they have a shoot at one end and roots at the other.

Light bulbs have two terminals because the filament needs to be part of a circuit so the electricity can flow. The terminals are where the electricity flows in and out.

Why do bulbs have two terminals?

One Terminal Is for Positive And Another Is Negative Wier . Bulb Can't Glow Until Both The Terminals Are Connected


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.


Which one is ground terminal on H3 bulb?

The ground terminal on an H3 bulb is typically the metal tab or contact on the base of the bulb. It is usually connected to the vehicle's grounding system to complete the electrical circuit.


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.

How would a meter be connected in a circuit too measure the voltage at a light bulb?

When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.

Does insulation tape helps to light the bulb?

ofcource it does.when we attach it to the positive terminal of the battery the bulb lights.


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.
