                                 English Ohm’s Law (ओहम का नियम) 🟩 1. Definition (English) Ohm’s Law states that: “The current flowing through a conductor is directly proportional to the voltage across its ends, provided the temperature and other physical conditions remain constant.” Mathematically :      V = I × R Where: V = Voltage (Volts) I = Current (Amperes) R = Resistance (Ohms, Ω) Electric Charge 🔹 English: Definition: Electric charge is the basic property of matter responsible for electric force. It can be positive or negative. Unit: Coulomb (C) Example: A proton has +1.6 × 10⁻¹⁹ C charge. An electron has −1.6 × 10⁻¹⁹ C charge. Voltage (Potential Difference) 🔹 English: Definition: Voltage is the electric potential difference between two points. It is the energy per unit charge. Formula: V = W / Q Unit...
