Why do pliers have plastic handles?
Plastic or rubber is an insulator which does not allow electric current to pass through it. The handles of the tools like screwdrivers and pliers used by electricians for repair have covering of plastic or rubber so that electric current may not pass through these tools to the body of the electrician to harm him.
Which material is used for making the handles of screwdrivers and pliers?
In most cases, the handle of a screwdriver is made up of plastic. Apart from plastic, many times the handles are also made from wood or metal. Plastic still remains the first choice. This main reason for this that plastic handles provide a better grip which doesn’t affect the efficiency.
Why do electricians use screwdrivers that have thick rubber handles?
Why do electricians use screwdrivers that have thick rubber handles? If handles of electric tools don’t have any cover, electricity can transfer from tools to the body and electrician and can give him shock.

What is electrical device example?
Some examples of electrical devices include light bulbs, vacuums, toasters and older technologies such as the electric telegraph and batteries. Electrical devices are defined as devices that use or generate electricity and transform it into another form of energy, such as motion, heat or light.
Is fan an electronic device?
A fan is also an example of a simple electrical device that converts electrical energy into kinetic energy putting the fan in motion. Such a device is simple and does not require any manipulation of the current that is given to it. On the other hand, a thermostat is an example of an electronic device.
Is a phone an electrical device?
A mobile device is an electronic device which its user can easily carry with them. Typical examples are a mobile phone, PDA and handheld game consoles. Mobile devices do not need an external power supply to work. Usually, they have a battery to hold electricity to work without electric wires.
What is considered an electrical device?
1. electrical device – a device that produces or is powered by electricity. antenna, transmitting aerial, aerial – an electrical device that sends or receives radio or television signals. attenuator – an electrical device for attenuating the strength of an electrical signal.
What is the difference between an electronic device and an electrical device?
An electric device is one that directly uses electrical energy to perform a task. Instead of just converting electrical energy into light, heat, or motion, electronic devices are designed to manipulate the electrical current in ways that adds meaningful information to the current.
Is computer an electrical device?
A computer is an electronic machine that processes raw data to give information as output. A computer is described as an electronic device because; it is made up of electronic components and uses electric energy (such as electricity) to operate.
