Georg Simon Ohm was famous for publishing a formula in 1827. What does it describe?

Correct option is C

​The correct answer is (c) The current flow is proportional to potential difference and inversely proportional to resistance.

Explanation:

• Georg Simon Ohm was a German physicist who formulated Ohm's Law in 1827.
• Ohm's Law states that the electric current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to the resistance (R) of the conductor.
• The mathematical expression of Ohm’s Law is:

                      V=IR

where:

• V = Voltage (in Volts)
• I = Current (in Amperes)
• R = Resistance (in Ohms, Ω)
• This law forms the basis of electric circuits and electrical engineering and is crucial in analyzing and designing electrical systems.

Ohm's Contribution to Physics:

• Ohm’s research in electrical resistance led to the concept of Ohm’s Law, which is fundamental in circuit theory.
• He was the first to establish the relationship between voltage, current, and resistance.
• The SI unit of resistance, the ohm (Ω), is named in his honor.

Practical Applications of Ohm’s Law:

• Used in designing electronic circuits and electrical appliances.
• Helps in calculating resistance, current, and voltage in an electric circuit.
• Used in power transmission to ensure efficiency and safety.

Additional Knowledge:

• Kirchhoff’s Current Law (KCL), which states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction.
• Gauss’s Law, which states that the total electric flux through a closed surface is proportional to the charge enclosed within the surface.
• Faraday’s Law of Electromagnetic Induction, which states that the induced EMF (Electromotive Force) in a coil is directly proportional to the rate of change of magnetic flux through it.
