What carries electric current the best?
MetalsMetals like copper, silver and gold are very good conductors of electricity, that is, electrons may flow freely in those and most other metals because of how electrons are arranged around their nuclei. Other materials, like most plastics and ceramics, glass, rubber and teflon behave in the opposite way.
Which of the following devices converts light energy into electrical?
photocellA photocell gives out electric current when light is incident on it. So, it converts light energy into electrical energy.
What can be used to store an electrical charge?
A device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator is known as capacitor.
What is the process called when wire conductors are coated with solder?
Tinning is a process of using a soldering iron to melt solder around a stranded electrical wire. Tinning the tips of stranded wires holds the fine wires together and makes it easy to connect them to screw terminals or other connectors. This also ensures that all of the wires are making an electrical connection.
What is the device that converts electrical energy to heat energy?
An electric heater is an electrical appliance that converts electrical energy into heat. The heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy.
What is an electric circuit class 6?
Answer: The electric circuit is an arrangement that provides a pathway for the flow of electric current. It is a device comprising of switches, bulbs, wires and an electric cell.
What is a capacitor used for?
capacitor, device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. A simple example of such a storage device is the parallel-plate capacitor.
What does a capacitor store?
capacitor An electrical component used to store energy. Unlike batteries, which store energy chemically, capacitors store energy physically, in a form very much like static electricity.
Is capacitor a charge storing device?
A capacitor is a device for storing charge. It is usually made up of two plates separated by a thin insulating material known as the dielectric. One plate of the capacitor is positively charged, while the other has negative charge.

How to know if a circuit is overloaded?
You’ll surely know a current overload has occurred once you notice you’ve lost power to your lights, devices, and appliances. However, there are some signs that can help you determine if your circuit is taking on too much power. These are just a few ways you can spot an overload current before it happens: 1 Dimming or flickering lights 2 A buzzing sound coming from outlets or switches 3 Warm or hot outlets and switch covers 4 Burning odors from outlets or switches 5 Burnt damage on plugs or outlets 6 Devices, tools, and appliances not operating at full power
Why is it important to invest in a circuit breaker?
It’s crucial to invest in a component that protects your circuits from damage and helps maintain your electrical current flow. As mentioned above, the circuit breaker and fuses are in place to manage current overloads and prevent them from causing further damage to your home.
What is a breaker in a circuit?
Breakers are designed to cut off the electrical flow if the power exceeds safe levels. One of your best bets to protect against an overload circuit is to have a breaker in place and ensure your fuse lines are all intact.
Why does my light turn off automatically?
This occurs when your electrical circuit has more electricity than it can handle and will cause the current to completely cut off and your lights or plugged in devices and fixtures will turn off automatically.
