According to Ohm’s law,
The current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged.
Mathematically it can be represented as,
Potential difference ∝ Current
V ∝ I (So when the value of V increases then the value of I also increases simultaneously)
V = IR
Where,
V is Voltage in volts (V)
R is Resistance in ohm (Ω)
I is Current in Ampere (A)
It is very important to remember this formula, so that if any two values of the resistance, voltage or current quantities are given then we can use Ohm’s law to find out the third missing value.
Formulae:
To find Voltage(V),
V = IR
To find Current(I),
To find Resistance(R),
Ohm’s law relationship can also be remembered using pictures. So, to easily remember this formula there is another way called Ohm’s magic triangle. The magic V I R triangle can be used to calculate all formulations of ohm’s law.
Ohm’s Law Magic Triangle:
The triangle for Ohm’s law is
If the value of Voltage is asked and the values of the current and resistance are given, then to calculate voltage simply cover the We are left with the I and R or I X R. So, the equation for Voltage is Current multiplied by Resistance.

Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance",
