Two parallel conductors- are 4cm apart in air medium. If 25 Amp and 5 Amp be the current through them, what length of the conductor will experience a force of 0.125 dyne.

Two very long conducting wire are kept at a distance 4 cm from each other in vacuum. Currents flowing through the wires are 25A and 5A, respectively. Find the length of each conductor, which experiences a force of 125 dynes ?

Two conductors are connected in parallel combination. The ratio of the currents flowing through them is 3:5. The ratio of their resistance is :

Resistance of a conductor is 200 Omega and the current through it is 10 mA,What is the potential difference across the two ends of the conductor?

The area of parallel capacitor with air as dielectric medium is 125.6 cm^2 and the separation between the two plates of the capacitor is 2 cm. What will be the radius of a sphere having its capacitane equal to that of the parallel plate capacitor?

The resistance of a conductor is twice than another. What will be the ratio of current flow through them under same potential difference.

Through each of two long straight parallel conducting wires kept 4 cm apart, 10 A current is flowing. If the direction of current in the wirs are mutually opposite, what will be the magnitude of magnetic field produced at a point just midway between the two wires?

A rectangular conductor LMNO is placed in a uniform magnetic field of 0.5 T. The field is directed perpendicular to the plane of the conductor. When the arm MN of length of 20 cm is moved towards left with a velocity of 10 m . s^(-1) , calculate the emf induced in the arm. Given the resistance of the arm to be 5 Omega , (assuming that the other arms are of negligible resistance) find the value of the current in the arm.
