I-V characteristic curve for a p-n junction Aim To draw the I-V characteristic curve for a p-n junction diode in forward and reverse bias. Apparatus and Material Required Principle Procedure Caution Never increase the value of the voltage too much across the diode. Excessive current flow may damage the diode if it exceeds its limit. Maximum…
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 \(\vec {v_d} \)….

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…
