Are you looking for an answer to the topic “How is Ohm’s law verified?“? We answer all your questions at the website Chiangmaiplaces.net in category: +100 Marketing Blog Post Topics & Ideas. You will find the answer right below.
When a resistor is kept at a constant temperature, its resistance will remain unchanged. We can confirm this experimentally by connecting a resistor to a power supply and measuring the current in the resistor as the supply voltage is increased.Record the readings of the ammeter and voltmeter. Take atleast six sets of readings by adjusting the rheostat gradually. Plot a graph with V along x-axis and I along y-axis. The graph will be a straight line which verifies Ohm’s law.Expert-verified answer
Ohm’s law states that Current through a conductor is directly proportional to voltage difference across it. where V is the voltage, I is the current and R is the resistance. The circuit diagram to verify ohm’s law is drawn below. Voltmeter across a resistor is connected in parallel.
