In Ohm's Law, current is defined as the amount of electric charge that flows through a conductor per unit of time. It is denoted by the symbol "I" and is measured in amperes (A). Mathematically, Ohm's Law is expressed as:
=
I=
R
V
where:
I is the current in amperes (A).
V is the voltage across the conductor in volts (V).
R is the resistance of the conductor in ohms (Ω).
In simple terms, Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This law is fundamental in understanding and analyzing electrical circuits and is widely used in electrical engineering and electronics.
