Ohms Law: V=IR

Let us say, a 10 ohm resistor is connected to 9 Volts battery then Current flowing through resistor will be 9/10=0.9A as we know I=V/R

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them

Ohm's Law for DC Circuits

Current:

I = E/R = P/E

Voltage:

E = I*R = P/I

Resistance:

R = E/I = P/(I*I) = (E*E)/P

Power:

P = (I*I)*R = E*I = (E*E)/R
