Preparing for IIT JEE and NEET exams? Mastering crucial physics formulas is key. Dive into essential formulas for:
- Alternating Current (AC): Understand AC circuits with vital formulas like:
- Impedance (Z) Formula: Z = R + XL – Xc, where R is resistance, XL is inductive reactance, and Xc is capacitive reactance.
- Current (I) Formula: I = V/Z, where V is voltage and Z is impedance.
- Power (P) Formula: P = I²R, essential for power calculations in AC circuits.
- Resistance: Delve into foundational electrical formulas:
- Ohm’s Law Formula: V = IR, connecting voltage (V), current (I), and resistance (R).
- Power (P) Formula: P = IV = I²R = V²/R, crucial for power calculations in resistive circuits.
- Circular Motion: Master dynamics with key circular motion formulas:
- Centripetal Acceleration (a) Formula: a = v²/r, where v is velocity and r is radius of circular motion.
- Centripetal Force (F) Formula: F = ma = mv²/r, crucial for understanding the force required to keep an object in circular motion.
- Rigid Body Dynamics: Delve into mechanics with essential rigid body formulas:
- Moment of Inertia (I) Formula: I = Σmr², where m is mass and r is the distance from the axis of rotation.
- Torque (τ) Formula: τ = Iα, linking torque (τ) to moment of inertia (I) and angular acceleration (α).
