Steps to execute Ohm's law experiment
Steps to execute Ohm's law experiment1> We have to start the test with a single cell. We have to connect the circuit as shown in Figure a. – The ammeter will show us the current I flowing through the circuit, and the voltmeter will measure the potential difference V between the ends A and B of the wire.
hope it will help you friend ✌️✌️✨ XD...
Answer:
Ohm’s law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it. Georg Simon Ohm, a German physicist was the first to verify Ohm’s law experimentally.
Ohm’s Law Explanation
Ohm's Law
One of the most basic and important laws of electric circuits is Ohm’s law.
Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant
Explanation:
Mathematically, this current-voltage relationship can be written as,
Ohm's Law Equation
In the equation, the constant of proportionality, R is Resistance and has units of ohms, with symbol Ω.
The same formula can be rewritten in order to calculate the current and resistance respectively as follows:
Ohm's Law Equation
Ohm's Law Equation
Ohm’s law only holds true if the provided temperature and the other physical factors remain constant. In certain components, increasing the current raises the temperature. An example of this is the filament of a light bulb, in which the temperature rises as the current is increased. In this case, Ohm’s law cannot be applied. The lightbulb filament violates Ohm’s Law.
Ohm’s Law Statement: Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.
Ohm’s Law Equation: V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
