Named after Georg Simon Ohm, Ohm's Law deals with the relationships between the Electromotive force Voltage (E), Current (I) and Resistance (R), in an electrical circuit.
The law is E=I x R.

ōm) [for G. S. Ohm], law stating that the electric current i flowing through a given resistance r is equal to the applied voltage v divided by the resistance, or i=v/r. For general application to alternating-current circuits where inductances and capacitances as well as resistances may be present, the law must be amended to i=v/z, where z is impedance. There are conductors in which the current that flows is not proportional to the applied voltage. These do not follow this law and are called nonohmic conductors

The current in a circuit (meaured in amperes or amps) equals the voltage (in volts) divided by the resistance (in ohms).

If you but 200 volts through a 10 ohm resistor, you will get 20 amps of current. Make the resistor 100 ohms, and you only get 2 amps.

Ohm's law : so long as the physical state of a conductor remains same ,the potential difference applied between the ends of the conductor bears the constant ratio to the electric current passing through it.

Ohm's Law

Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere

ohm's law is a basic law of current electricity
it states that "at constant temperature and pressure, the potential difference across a wire is directly proportional to the current passing through the wire"
thus, the more potential difference (pd) across the ends of a wire, the more the current

ohms law states that- the current passing thru a conductor is directly proprotional 2 the potential diff across it's ends

ohm's law states that current is inversely proportional to the resistence in circuit.ie I=V/R
V=voltage applied across the circuit
I=current produced
R=resistence for the current
as we increase resistence in circuit it opposes the motion of free electrons and in turn current decreases bcoz current flows due to free electrons it means as resistence increases current decreases and if resistence decreases current increses.

I = E/R
E = I x R
R = E/I
P = E x I
R = E^2/P
E = P/I
I = P/E
R = P/I^2

E = Voltage
R = Resistance
I = Current in Amperes
P = Power in Watts

Ohm's law is a way to calculate one value in a circuit if you know the other 2.

Be back.

Here I am.

All answers are good they have use different interpretation to answer your "Q?", they also have used different symbols for same parameter.

Even the definition language is different.

After all this if you get more confused, then go back to your books and specifically ask what you do not understand that is printed in the book. Make sure you print word by word what the book has in it.

I hope this will help you in some ways.
