What are the two terminals of the bulb?
The two terminals of a light bulb are the positive terminal, typically connected to the center post or button at the bottom of the bulb, and the negative terminal, usually connected to the screw base or outer metal casing.
Why does a battery corrode?
Batteries, specifically wet cell batteries, mostly corrode due to leaks in their casings. These leaks allow the material inside the battery to seep out and contaminate the battery's metallic casing. This leaked material acts as a catalyst for the oxidation of the metallic casing of the battery, otherwise known as corrosion.
What is the function of the metal casing and tip of a bulb?
The metal casing of a bulb provides structural support and acts as a heat sink to dissipate heat generated by the bulb during operation. The metal tip is the electrical contact point for the bulb, allowing electricity to flow into the bulb and power the light-emitting element inside.
What part of the toaster would you expect the earth wire to be connected?
The earth wire would typically be connected to the metal casing of the toaster. This is to provide a safe path for electric current to flow in case of a fault, protecting users from electrical shock.
What is the difference of a battery and a lemon battery?
A regular battery uses chemical reactions inside a closed casing to produce electricity, while a lemon battery uses the acidic juice of a lemon as an electrolyte to generate a small amount of electricity through a chemical reaction between the lemon juice and metal electrodes placed in the lemon. Lemon batteries are typically used for educational purposes to demonstrate basic concepts of electricity generation.
Will a light bulb light if its metal tip rests on metal casing?
No, a light bulb will not light if its metal tip rests on a metal casing. The metal tip of the light bulb needs to be connected to the electrical circuit in order for it to light up. Resting on metal casing would not provide this connection.
Which part of the electric kettle is the earth wire connected?
the metal casing of the electric kettle
What is the function of the metal casing and tip of the bulb?
The metal casing of a light bulb serves as a protective barrier, preventing the bulb from breaking easily and protecting the delicate inner components from damage. The metal tip is where the electrical contact is made to supply power to the bulb, allowing the electricity to flow through the filament or LED inside the bulb, which then produces light.
What are five main materials that make up a flashlight?
The main materials of a flashlight are:a lensa light bulb with wires to metal contactsa batterymetal contacts between the battery and bulba plastic or a metal casing
How do you recharge a 12 volt battery?
With a 12 volt battery charger. Red + connected to + post on battery. Black - connected to any metal part of the vehicle. You do not have to remove the battery from the vehicle.

The two terminals of a light bulb are the positive terminal, typically connected to the center post or button at the bottom of the bulb, and the negative terminal, usually connected to the screw base or outer metal casing.
Is a torch connected in series or parallel?
A torch typically has its battery connected in series with the light bulb, creating a simple circuit. This means the electrical current flows from the battery through the bulb and back to the battery in a continuous loop, allowing the light to work.
Which part of the of a washing machine should the earth wire be connected to?
The earth wire of a washing machine should be connected to the metal chassis of the machine to prevent electric shock and ensure safety.
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.
Why doesn't a doctors stethoscope use a battery to amplify sound?
it doesnt need battery because the metal is connected to it.
What is the first flashlight?
The first flashlight was invented by Joshua Lionel Cowen in 1898. It used a dry cell battery, a small incandescent light bulb, and a metal casing, making it portable and convenient for use in various situations.
