Important Formulas for CBSE Class 10 Science Exam 2026
To make your study notes easy to edit, here are the essential formulas for the February 25, 2026, Science board exam.
-
Mirror Formula: 1/f = 1/v + 1/u (where f = focal length, v = image distance, u = object distance)
-
Lens Formula: 1/f = 1/v - 1/u
-
Ohm's Law: V = I * R (where V = Potential Difference, I = Current, R = Resistance)
-
Resistors in Series: Rs = R1 + R2 + R3 + ...
-
Resistors in Parallel: 1/Rp = 1/R1 + 1/R2 + 1/R3 + ...
-
Joule’s Law of Heating: H = I^2 * R * t
-
Electric Power: P = V * I (or P = I^2 * R or P = V^2 / R)
-
Magnification (Mirror): m = h'/h = -v/u
-
Magnification (Lens): m = h'/h = v/u
-
Refractive Index (Snell's Law): n = sin i / sin r
