## What is Ohm’s law class 10?

Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Current is directly proportional to voltage difference through a resistor.

## What is the value of 1 ampere?

One ampere of current represents one coulomb of electrical charge, i.e. 6.24×1018 charge carriers, moving in one second. In other words, “an ampere is the amount of current produced by the force of one volt acting through a resistance of one ohm”.

## What is the SI unit of resistance?

The SI unit of electric resistance is the ohm (Ω). 1 Ω = 1 V/A.

## What is the unit of mirror?

In a spherical mirror: The distance between the object and the pole of the mirror is called Object distance(u). The distance between the image and the pole of the mirror is called Image distance(v). The distance between the Principal focus and the pole of the mirror is called Focal Length(f).

## What is image distance?

Image Distance, s’, is the distance from a lens or mirror to an image. • Magnification, m, is the amount of size increase (or decrease) of the image as compared to the object. m = hi /ho • Images are formed by lenses and mirrors where light rays cross or focus.

## What is V in lens formula?

where u is the distance of the object from the lens; v is the distance of the image from the lens and f is the focal length, i.e., the distance of the focus from the lens. N.B. other sign conventions are sometimes used in the literature. = 2 6 − 1 6 = 1 6 So v = 6 cm.

## What are the 6 types of lenses?

• The Standard Prime Lens. The Standard Prime Lens (or just Prime Lens) provides a fixed focal length.
• The Zoom Lens. Speaking of Zoom Lenses, the Zoom Lens might be your catchall lens.
• The Fisheye Lens.
• The Wide Angle Lens.
• The Telephoto Lens.
• The Macro Lens.

## What is power of a lens?

The power of a lens is defined as the reciprocal of its focal length. It is represented by the letter P. The power P of a lens of focal length f (in m) is given by. P=1f. The SI unit of power of a lens is ‘dioptre’.

## What is C in lens?

(c) Optical centre: It is the central point of the lens. Represented by 0. (d) Focus: The point at which rays of light parallel to principal axis converges (convex lens) or appears to diverge (concave lens) after refraction.

## How do you get a 95 in Science class 10?
