Ohm's Law|Resistance|Question

Two resistance wires on joining in parallel the resultant resistance is ohms (6)/(5) ohms. One of the wire breaks, the effective resistance is 2 ohms . The resistance of the broken wire is

To find the value of resistance R using Ohm's law, we are given four voltmeters as below. Which one will you prefer to be connected in the circuit?

Currrent Density | Ohm's Law |Resistance and variation of resistance with temp.

A wire has resistance 12 ohms. If it is bent in the form of a equilateral triangle. The resistance between any two terminals in ohms is:

Graph showing the variation of current versus voltage for a material GaAs is shown in figure. Identify the region of (i) negative resistance (ii) where Ohm's law is obeyed.

In the given circuit, the resistances are given in ohm. The current through the 10Omega resistance is 3 A while that through the resistance X is 1 A. No current passes through the galavanometer. The values of the unknown resistances X and Y are respectively (in ohm)
