Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A).
It is the rate of flow of electric charge through a conductor.
Current flows from the positive terminal to the negative terminal in a circuit.
There are two types of current - direct current (DC) and alternating current (AC).
- Q2. How calculate conductors dia.
- Ans.
Conductors diameter can be calculated using the formula: diameter = sqrt((4 * area) / pi)
Calculate the area of the conductor (usually circular) using the formula: area = pi * (radius^2)
Determine the radius of the conductor
Use the formula: diameter = sqrt((4 * area) / pi) to calculate the diameter
