Q6. What is current
Current is the flow of electric charge through a conductor.
Current is measured in amperes (A)
It is caused by the movement of electrons
Current can be either direct current (DC) or alternating current (AC)
Examples of current include the flow of electricity through a wire or the current in a battery
Q7. What is omhs law
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Ohm's law is a fundamental principle in electrical engineering.
It states that the current flowing through a conductor is directly proportional to the voltage applied across it.
The proportionality constant is known as the resistance of the conductor.
Ohm's law can be expressed mathematically as I = V/R, where I is the current, V is the voltage, ...read more
Q8. Grade of concrete Grade of steel
Grade of concrete and steel are important factors in construction.
Grade of concrete refers to the strength of the concrete mix, which is determined by the ratio of cement, sand, and aggregate.
Common grades of concrete include M10, M20, M30, and M40, with M40 being the strongest.
Grade of steel refers to the strength and quality of the steel used in construction.
Common grades of steel include Fe250, Fe415, and Fe500, with Fe500 being the strongest.
The grade of steel used in con...read more
