Sure, here are the definitions of the basic SI units related to electricity and magnetism:
Electric Charge (Coulomb, C):
The SI unit of electric charge is the Coulomb (C). One Coulomb is defined as the amount of electric charge that flows through a conductor when a current of one Ampere (A) flows for one second.
Electric Current (Ampere, A):
The SI unit of electric current is the Ampere (A). One Ampere is defined as the flow of one Coulomb of charge per second through a conductor.
Voltage or Electric Potential Difference (Volt, V):
The SI unit of voltage or electric potential difference is the Volt (V). One Volt is defined as the electric potential difference across a conductor when one Joule of work is done to move one Coulomb of charge from one point to another.
Electric Resistance (Ohm, Ω):
The SI unit of electric resistance is the Ohm (Ω). One Ohm is defined as the resistance of a conductor in which a current of one Ampere flows when a voltage of one Volt is applied across it.
Electric Capacitance (Farad, F):
The SI unit of electric capacitance is the Farad (F). One Farad is defined as the capacitance of a capacitor that stores one Coulomb of charge when a potential difference of one Volt exists between its plates.
Magnetic Flux (Weber, Wb):
The SI unit of magnetic flux is the Weber (Wb). One Weber is defined as the magnetic flux that produces an electromotive force of one Volt when it is reduced to zero at a uniform rate in one second.
Magnetic Field Strength (Ampere per meter, A/m):
The SI unit of magnetic field strength is Ampere per meter (A/m). It represents the strength of a magnetic field produced by a current-carrying conductor.
Magnetic Induction or Magnetic Flux Density (Tesla, T):
The SI unit of magnetic induction or magnetic flux density is the Tesla (T). One Tesla is defined as the magnetic flux density that produces one Weber of magnetic flux per square meter perpendicular to the direction of the flux.
These units are fundamental to understanding and working with electrical and magnetic phenomena in physics and engineering.
