Aim To find resistance of a given standard resistor using metre bridge. Apparatus and Material Required Description of the Apparatus Meter BridgeMeter bridge consists of one-meter-long constantan wire with uniform cross-sectional area and three thick metal strips, two bent at ninety-degree angles. Mounted on a wooden board marked with a scale, these components create a setup…
Aim To determine resistivity of two wires by plotting a graph for potential difference versus current. Apparatus and Material Required Principle According to Ohm’s Law, the current passing through a conductor is directly proportional to the voltage applied across it, as long as the conductor’s temperature and other physical properties remain constant. If I be the…

Force Definition: A push or pull acting on a body which tends to change its state of rest or motion. Types: Effects of Force: Unit of Force Resultant Force Balanced and Unbalanced Force Types of Forces Pressure Definition: Force acting on a unit area. \[\text {Pressure} = \frac {Force}{Area}\] Unit: Pascal (\(\text{Pa}\)), also called newton…
Frequently Asked Questions (FAQs) on Motion Q1: What is motion? Ans: Motion is the change in an object’s position with time. It can be observed directly, such as a car moving, or inferred indirectly, like the movement of dust particles indicating air motion. Q2: How can we describe the position of an object? Ans: The…
Force between Two Parallel Current-Carrying Wires Consider two parallel wires, \( a \) and \( b \). A current \( I_a \) passes through wire \( a \) and a current \( I_b \) passes through wire \( b \). The distance between them is \( d \). The current \( I_a \) creates a…
How much force a uniform magnetic field applies on a current carrying conductor Magnetic force on a current-carrying conductor Let a current \( I \) flow in a conductor having cross-sectional area \( A \). The number density of mobile charge carriers (electrons) is \( n \) and their drift velocity is \(\vec {v_d} \)….
Force on a moving charge in a uniform magnetic field If a charge \( q \) moves with a velocity \(v\) in a zone of uniform magnetic field \(\vec{B}\), it experiences a force given by:\[ \vec{F_B} = q \vec{v} \times \vec{B} \] \[ \vec {F_B} = q \ v\ B \sin \theta \ \hat n\]…
