Clear all your doubts with just one tap only on INDIETAP

Physics is a branch of science that deals with the facts about matter and motion and includes the subjects of mechanic, heat, light, electricity, sound and the atomic nucleus. Physics is related to our daily life needs. Physics deals with nature and natural phenomenon.

Make your kids learning easy with Indietap understand each concept of Physics like fluid mechanics, thermodynamics, newton's law of motion, electricity and magnetism. Clear all your doubts with just one tap only on INDIETAP.

WHAT IS AMPERE? –

Ampere or 'amp' is a unit of electric current denoted by A. It is named after the French Physicist and Mathematician Andre-Marie Ampere, who is known as the 'Father of Electrodynamics'. The rate of electron flow in an electrical conductor is measured in Ampere. One Ampere of current represents one Coulomb of electrical charge, i.e. 6.24×1018 charge carriers, moving in one second. In other words, an ampere is the amount of current produced by the force of one volt acting through a resistance of one ohm. It is one of the seven basic SI units. It is to be noted that Ampere and Coulomb are two different units. Coulomb is also called as Ampere – second or Ampere – hour. As per SI units, constant and average current are expressed in Amperes. The relationship between Ampere and Columb is given as follows:

Ampere = 1 Coloumb/second

Ampere can be defined as:

The unit of electric current that is equal to the flow of one Coulomb per second

At any given point in an area experiencing current, if the charge on particles moving through it increases, the Ampere value will increase proportionately.

HISTORY OF AMPERE:

The original Ampere definition was different. It used to be one-tenth of the unit of electric current in centimetre – gram – second system of units. Now, those units are called abampere, which is defined as the amount of current that produces a force of two dynes per centimetre of length in between two wires that are at a one-centimetre distance.

AMPERE CONVERSION:

Unit conversion is crucial in solving problems. Below is the list of ampere conversion from one scale to another.

Conversion of amps (A) to kiloamps(kA):

One kiloamp (kA) is equal to a thousand amps (A).

1 kA = 1000 A or 1 × 103 A

For example, 5 amperes of current can be converted to kiloamperes as follows:

5 A × 1000 = 5000 A or 5 kA

Conversion amps (A) to milliamps (mA):

One milliampere is equal to 1000 amperes.

1 mA = 1000 A

For example, 2 A to milliampere is converted as follows:

2 A/1000 = 0.002 A or 2 × 10-3 A = 2 mA

Conversion of amps (A) to microamps (µA):

One Ampere is equal to 1000000 or 10-6 microamperes.

1 µA = 1000000 A

For example, 5 A is converted to microamps as follows:

5 A / 1000000 = 0.000005 A or 5 × 10-6 A = 5 µA
