Ohms law "V= RI" is the " F=ma or Newton's Law" of Electricity. It gives the quantitative relationship between the three important concepts of electricity, V=Voltage, I= Current and R= Resistance.
AnswerOhm's Law is not really important at all, as it is not universal and applies to very few conductors and, then, only under very strict conditions. For a circuit to obey Ohm's Law, its ratio of voltage to current must remain constant for variations in voltage, and this is rarely the case! Most conductors, and most electric devices such as diodes, etc., simply do not obey Ohm's Law. In fact, some engineers and scientists would argue that Ohm's 'Law' should not be a law at all as it applies in so few circumstances.
The problem is that many people, including many electricians, mistakenly think that Ohm's Law is represented by an equation that tells us the resistance is voltage divided by current whereas, in fact, this equation is derived from the definition of the ohm, and NOT from Ohm's Law.
Unit measure for resistence is called as "OHM". Its law is called as "OHM'S LAW".
the entire branch of electricity uses this ohms law in building their circuits..........the voltage and current relations are being brought using this ohms law also many other laws are based upon this law only.
Yes, the strength of an electric field decreases as the distance from the electron increases. This is governed by the inverse square law, which states that the electric field strength is inversely proportional to the square of the distance from the source.
Ohm's Law is not applicable to open circuits because there is no current flow. Ohm's Law specifically describes the relationship between voltage, current, and resistance in a closed electrical circuit.
Here are some practice questions based on Ohm's Law: If a resistor has a resistance of 10 ohms and a current of 2 amperes flowing through it, what is the voltage across the resistor? A circuit has a voltage of 12 volts applied across a resistor with a resistance of 4 ohms. What is the current flowing through the resistor? If a circuit has a current of 0.5 amperes flowing through a resistor with a resistance of 8 ohms, what is the voltage across the resistor? These questions will help you practice applying Ohm's Law to calculate voltage, current, and resistance in electrical circuits.

3 amperes. Ohm's law: Voltage is ohms times amperes.
ohms law.
Ohm's law: Current is voltage divided by resistance. 50 volts divided by 5 ohms = 10 amperes.
Ohm's most important discovery was in 1826 when he discovered the mathematical law of electric current called Ohm's law.
The ohm is a measure of electrical resistance. It was named for the German physicist Georg Ohm.
Ohm's Law states that V = IR (voltage = current times resistance). It can be used to find any of those three quantities if the other two are known. It is one of the most important formulae for calculations in electrical circuits - you will use it all the time.
Unit measure for resistence is called as "OHM". Its law is called as "OHM'S LAW".
To find the conductance using ohms law,you take the inverse of the resistance(/R)
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
You may find it helpful to use Ohm's law and the definition of electrical power.
