​Which two fundamental electrical quantities are related by Ohm's Law?

Correct option is C

The correct answer is (c) Voltage and current

Explanation:

Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The law is expressed by the formula:

                                                                                                  $$\boxed{V = I \times R}$$​

Where:

• V = Voltage (Volts)
• I = Current (Amperes)
• R = Resistance (Ohms)

So, Ohm’s Law directly relates Voltage and Current, making option (c) the correct answer.

Information Booster:

Key Concepts of Ohm’s Law:

•  It helps calculate any one of the three quantities (V, I, R) when the other two are known.
• Widely used in circuit analysis and design.
• Applicable only to ohmic materials (where resistance remains constant).
