unit

The strength of the current is described by the current intensity, which is the amount of charge passing through a certain cross-section of the conductor per unit time, referred to as the current, and is represented by I.

The current intensity is a scalar quantity, and it is customary to specify the direction of movement of the positive charge as the direction of the current. In a conductor, the direction of current flow is always in the direction of the electric field from high potential to low potential. In the International System of Units, the unit of current intensity is the ampere (A), which is one of the seven basic units in the SI system.

Some common currents: 1.5μA~2μA for electronic watches, 200mA for incandescent bulbs, 100mA for mobile phones, 5A~10A for air conditioners, 200A for high voltage electricity, and 20000A~200000A for lightning.

Define formula: . That is: in a period of time Δt, the amount of charge ΔQ passing through the cross section of the conductor, the unit is Coulomb; Δt is the time for the charge to pass through the conductor, the unit is seconds.

direction

Physically specify the direction of the current, which is the direction of the directional motion of the positive charge (that is, the positive direction of the directional motion of the positive charge or the opposite direction of the speed of the directional motion of the negative charge). The direction of current movement is opposite to the direction of electron movement.

Charge refers to free charge, which is free electrons in metal conductors, and positive and negative ions in aqueous solutions of acids, bases, and salts.

Outside the power supply, the current flows from the positive to the negative, and inside the power supply from the negative to the positive.
