Ohm's Law is made from3 mathematical equations that shows the relationship between electric voltage, current and resistance.

V = I x R  (Voltage = Current multiplied by Resistance)

R = V / I  (Resistance = Voltage divided by Current)

 I = V / R  (Current = Voltage Divided by Resistance)

Ohms law is voltage= current( I ) X resistance (R)

I=V\\R

I is for current

v is for voltage

r is for resistance

voltage across a conductor is directly proportional to current flowing into the conductor, the constant of proportionality is resistance 

V=IR

R=V/I

 

resistance is directly proportional to voltage and inversely proportional to current as stated in equation

Ohm's Law Formula / Equation When we know the voltage and resistance, we can calculate the current. Ohm's law definition The resistor's current I in amps (A) is equal to the resistor's voltage VR=V in volts (V) divided by the resistance R in ohms (Ω): V is the voltage drop of the resistor, measured in Volts (V). In some cases Ohm's law uses the letter E to represent voltage. E denotes electromotive force. I is the electrical current flowing through the resistor, measured in Amperes (A) R is the resistance of the resistor, measured in Ohms (Ω) Voltage calculation When we know the current and resistance, we can calculate the voltage. The voltage V in volts (V) is equal to the to the current I in amps (A) times the resistance R in ohms (Ω): V=I\\times R Resistance calculation When we know the voltage and the current, we can calculate the resistance. The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A): R=\\frac{V}{I} Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that: If we increase the voltage, the current will increase. If we increase the resistance, the current will reduce.

V is the voltage drop of the resistor, measured in Volts (V). In some cases Ohm's law uses the letter E to represent voltage. E denotes electromotive force.

I is the electrical current flowing through the resistor, measured in  Amperes (A)

R is the resistance of the resistor, measured in Ohms (Ω)
