state Ohm's law three student X Y and Z while performing the experiment to study the dependence of current on a potential difference across a resistor connect the ammeter the battery the key and the resistor in series in the following three difference order
Answers
ohms law states that the current flowing through the conductor is directly propotional to the potential difference across the conductor for which the physical state and temperature remains same.
Answer:
Ohm's law : It states that the current flowing through the conductor in the circuit is directly proportional to the voltage across it,
i.e. I ∝ V
I = V/R
=> V = I R
where 1/R is the resistance is the proportionality constant which is the resistance of the circuit.
The V-I graph is a straight line with the slope equal to R.
The circuit for the experiment of ohm's law is constructed as follows:
1. Ammeter is connected in series with the resistor.
2. Voltmeter is connected in parallel with the resistor.
3. battery and key are connected in series before the resistor.
