Question

Is verification of ohm's law by Voltmeter-ammeter method and Potentiometer method both in ICSE syllabus of Physics of Class 10?

plz answer ASAP​

Answer 1

Verification of Ohm’s Law: Use the circuit as shown taking case the +ve of voltmeter and +ve of Ammeter should be connected to the +ve of battery and voltmeter in parallel key is closed and Rheostat is set to get the minimum reading in Ammeter and voltmeter. The rheostat is then gradually moved and each time value of A and V are noted. The ratio of V/I is always found constant. This verified ohm’s law.
