Determination of the Angle of Minimum Deviation for a given Prism Aim To determine angle of minimum deviation for a given prism by plotting a graph between angle of incidence and angle of deviation. Apparatus and Material Required Principle A triangular prism consists of three rectangular lateral surfaces and two triangular bases. The two lateral surfaces,…
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…
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…
