Which of the two wires mentioned in part (a) are at the same potential ?

Which two of the three wires of a household circuit are at the same potential ?

(a) Name two isotopes of uranium which are fissionable. (b) Which of the isotope mentioned in part (a) above is easily fissionable ? Give reason. (c ) State whether the neutron needed for fission reaction of the isotope mentioned in part (b) above, is slow or fast ?

Two wires 'A' and 'B' of the same material have their lengths in the ratio 1 : 2 and radii in the ratio 2 : 1 The two wires are connected in parallel across a battery. The ratio of the heat produced in 'A' to the heat produced in 'B' for the same time is

Consider two conductors. One of them has a capacity of 2 units and the capacity of the other is unknown. They are charged until their potential are 4 and 5 units respectively. The two conductors are now connected by a wire when their common potential is found to be 4.6 units. Then the unknown capacity has the value (in the same units as above)

Figure shows a part of the circuit. Which points have the same potential as that of point A:

When two wires have current in same direction then force is

Assertion : A and B are two conducting spheres of same radius. A being solid and B hollow. Both are charged to the same potential. Then, charge on A= charge on B. Reason : Potentials on both are same.

Two wires A and B have the same cross section and are made of the same material, but the length of wire A is twice that of B . Then, for a given load

Power generated across a uniform wire connected across a supply is H . If the wire is cut into n equal parts and all the parts are connected in parallel across the same supply, the total power generated in the wire is
