Verification of Ohms Law.
Verification of Ohms Law
Ohm's Law:
Ohm's Law states that the current passing through a conductor is directly proportional to the potential difference between its ends, provided the physical conditions such as temperature of conductor remain unchanged.
Experimental Verification Of Ohm's Law:
Set up a circuit as shown in figure below with a battery (B) to act as a source of electricity, a switch or a key (K) to control the flow of current in the circuit, a rheostat (Rh),to vary the resistance in the circuit, an ammeter (A) to measure the flow of current,, a resistor (R) across which a voltmeter (V) is connected to measure the potential difference. When ever the sliding terminal of the rheostat is moved the current in the circuit changes. We will follow the steps .given below to verify the Ohm's Law.
The graph of the current against the potential difference is plotted, it will be a straight line. This shows that the current is proportional to the potential difference.
Limitation of Ohm s Law
1. Ohm s law does not apply to conductors such as diode, radio valves, metal rectifiers, electricity through gases.
Students / Parents Reviews [10]
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

8thBeing a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
Prisha Gupta
8thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Barkha Arora
10thAbhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.

10thI have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
Yatharthi Sharma
10thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
