Explain ohms law ?
With diagram
Answers
Answer:
Ohm's law states that Current through a conductor is directly proportional to voltage difference across it.
IαV
⇒V = I R
where V is the voltage, I is the current and R is the resistance
Answer:
Ohm's law states that Current through a conductor is directly proportional to voltage difference across it.
IαV
⇒V = I R
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.
Ammeter to measure current in the circuit is attached in series. A variable resistor is connected. Changing the resistance would alter potential drop across the resistor which would affect the amount of current.
From the reading we find that I and V vary linearly.
