Question: How do you use electric current?

What devices use electric current?


  • transformer:step up or step down voltage.
  • motor:use electrical energy for mechanical operation.
  • generator:vice versa of motor.
  • resistor: opposes the flow of current.
  • inductor: stores energy in the form of electromagnetic waves.
  • capacitor: stores stores and release energy in the form of electrostatic field.

What is electric current in simple words?

An electric current is a flow of an electric charge between two points. Imagine it being like water in a river carrying energy. The electric charge in the electrons causes resistors in light bulbs and electric fires to heat up. It also creates magnetic fields in motors, inductors, and generators.

Why is current important?

Current is one of the most important and fundamental elements within electrical and electronic technology. The current flowing in a circuit can be used in a variety of ways from generating heat to causing circuits to switch, or information to be stored in an integrated circuit.

What are the 3 examples of electrical energy?

Specific examples of electrical energy include:

  • Alternating current (AC)
  • Direct current (DC)
  • Lightning.
  • Batteries.
  • Capacitors.
  • Energy generated by electric eels.

What devices use AC and DC?

Direct current is popular in applications that contains batteries, are charged by plugging an AC to DC adapter into a wall, or uses a USB cable to charge. Examples of these products are flashlights, cell phones, modern day televisions (these contain an adapter which converts AC power to DC power), and hybrid cars.

What is a current Kid definition?

Kids Definition of current (Entry 2 of 2) 1 : a body of fluid (as air or water) moving in a specified direction. 2 : the swiftest part of a stream. 3 : the general course : trend. 4 : a flow of electricity.

What is current simple answer?

Current is the flow of electrical charge carriers like electrons. Current flows from negative to positive points. The SI unit for measuring electric current is the ampere (A). One ampere of current is defined as one coulomb of electrical charge moving past a unique point in a second.

What is current in easy English?

An electric current is a flow of electric charge. The equation of current is: where is the current flowing is the change in electric charge is the change in time. The SI unit of electric current is the ampere (A). This is equal to one coulomb of charge in one second.

What is an electric current Grade 5?

Current electricity is the flow of small electric charges through a closed circuit. A power source, such as a battery, converts chemical energy to electricity. … Electricity flows through the circuit and through the electrical device, such as a light bulb, which causes it to work.
