Question

Is there a relationship between current and potential difference in an electric circuit? Verify OHM'S LAW by creating a circuit diagram and plot the graph for the circuit diagram.

Answer 1

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

Answer 2

$\huge\red{Answer:-}$

$\huge\pink{==>}$Current is directly proportional to electric potential difference and inversely proportional to resistance.

$\huge\purple{==>}$The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.The correct answer is Ohm's law.

$\huge\pink{==>}$The relationship between the potential difference across a conductor and current flowing through it is determined by Ohm's law. Ohm's law states that potential difference across a conductor is directly proportional to the current flowing through it.
