as shown in the figure. The least count of the scale used in the metre bridge is 1 mm. The unknown resistance is

Q5PhysicsUnit 12: Current Electricity

Kirchhoff's law of meshes is in accordance with law of conservation of:

Q6PhysicsUnit 12: Current Electricity

Assertion Total current entering a circuit is equal to leaving the circuit by Kirchhoff's law. Reason It is based on conservation of energy.

Q7PhysicsUnit 12: Current Electricity

Assertion Kirchhoff's junction rule can be applied to a junction of several lines or a point in a line. Reason When steady current is flowing, there is no accumulation of charges at any junction or at any point in a line.
