define ohms law?

Question

define ohms law?

Answer

One ohm is the resistance of a conductor in which the current of 1 ampere results when a potential difference of 1 volt is applied across it

Answer

Ôhm's láw: The potential difference V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it, provided its temperature remains the same...
OR...
At all physical conditions,V is directly proportional to I.
ie., potential difference is directly proportional to current....
V= IR.

Answer

V=IR,
Ohm's law--> Ohm's law states that the potential difference across a current carrying conductor is directly proportional to the product of the current and resistance.

Answer

According to ohm's law at a constant temperature the current flow in a conductor is directly proportional to the potential difference applied on its end

Answer

V=IR

Answer

Ohms law is given by george simon ohm. it states that at a constant temperature v is directly proportional to I
v directly proportional to I
v=I r , where r is resistance

Answer

Ohm's law was given by a German Physicist 'Georg Simon Ohm' in the year 1827. It gives a relationship between current I, flowing through a metallic wire and potential difference V, across its terminals. According to this law, { The electric current flowing through a conductor is directly proportional to the potential difference across its ends, providing the physical conditions (such as temperature) remain unchanged.} THE LINE THE CURLLY BRACKET IS THE OHM'S LAW. V directly proportional to I OR V = IR ( here R is the constant) R is the constant of proportionality called Resistance of the Conductor at a given temperature.

Answer

just remember that in this law electric current is directly proportional to voltage and inversely proportional to resistance..

Answer

What is Ohm's Law?
Ohm's Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage, current, and resistance in an electrical circuit.
Formula
The law is mathematically expressed as:
- V = I × R
Where:
- V = Voltage (Volts)
- I = Current (Amperes)
- R = Resistance (Ohms)
Key Components
- Voltage (V): The electrical potential difference between two points in a circuit. It is the driving force that pushes electric charges through the circuit.
- Current (I): The flow of electric charge, measured in amperes. It represents how much charge is flowing in the circuit.
- Resistance (R): The opposition to the flow of current, measured in ohms. It determines how much current will flow for a given voltage.
Understanding the Relationship
- Direct Proportionality: According to Ohm’s Law, current is directly proportional to voltage. Increasing voltage will result in an increase in current if resistance remains constant.
- Inverse Relationship: Resistance is inversely proportional to current. If resistance increases, the current will decrease for a constant voltage.
Applications
- Circuit Design: Ohm’s Law is crucial for designing and analyzing electrical circuits, ensuring that components operate safely within their limits.
- Troubleshooting: It aids in diagnosing electrical issues by allowing engineers to calculate expected currents and voltages in faulty circuits.
In summary, Ohm's Law is an essential tool for understanding and working with electrical systems, providing a clear framework for analyzing how voltage, current, and resistance interact.
