System of resistors Formula

System of resistors: Let’s study some basic examples to study the combination of resistors. Resistors in series: The equivalent resistance of combination of resistance connected in series is given by, 1) Equivalent resistance , Rs = R1 + R2 + R3 Resistors in parallel: The equivalent resistance of combination of resistance connected in parallel is […]

Electric power Formula

Electric power: Let us illustrate some examples on power in electric circuit. Electric power is defined as the rate of dissipation of electric energy or rate of doing work by the charges in an electric field. Ex.1) Electric fan of power 1500 watt connected to 220 volt supply, find current drawn by electric fan. Solution: […]

Ohm’s Law Formula

Ohm’s law: Ohm’s law stated that, the electric current flowing through the metallic conductor is directly proportional to the potential difference applied across terminals of conductor provided the physical conditions of conductor remains same. ∴V α I ∴ V = I R ∴ V/I = R (constant) The proportionality constant represented as ‘R’ is known […]

Refractive index Formula

Refractive index on the basis of speed of light. 1) Refractive index of medium 1 with respect to medium 2 is defined as the ratio of speed of light in medium 2 to the speed of light in medium 1, written as, 2) Refractive index of medium 2 with respect to medium 1 is defined […]

Power of lens Formula

Power of lens (P): 1) Power of lens is defined the reciprocal of focal length of lens SI unit of power of lens is 1/meter (per meter) or dioptre (D). Power of convex lens is positive, while that o concave lens is negative. 2) If ‘n’ number of lenses of different power P1, P2, P3,….. […]

Mirror formula

Mirror formula: If u = object distance, v=image distance and f = focal length of mirror,then the mirror formula is given by According to sign conventions we need to assume the distance as follows, Object distance, u= -ve , Image distance, v = -ve/+ve (depends upon the position of image) and Focal length, f= -ve […]

Lens formula

Lens formula: If u = object distance, v = image distance and f = focal length of lens,then the lens formula is given by According to sign conventions we need to assume the distance as follows, Object distance, u= -ve , Image distance, v = -ve/+ve (depends upon the position of image) and Focal length, […]
