"The resistance of a wire is 1 ohm". Explain the statement.

The resistivity of a wire

The resistance of a wire is R ohm. If it is melted and stretched to n times its original length, its new resistance will be

The resistance of a wire of iron is 10 ohm and temperature coefficient of resistivity is 5 xx 10^-3//.^@C , At 20^@C it carries 30 mA of current. Keeping constant potential difference between its ends. The temperature of the wire is raised to 120^@C . The current in mA that flows in the wire now is.

The resistance of a wire is R ohm. What will be its new resistance if it is stretched to n times its original length ?

The resistance of a wire is 'R' ohm. If it is melted and stretched to n times its origianl length, its new resistance will be (a) nR (b) R/n (c) n^(2)R (d) R/(n^(2))

The resistance of the wire is 121 ohm. It is divided into .n. equal parts and they are connected in parallel, then effective resistance is 1 ohm. The value of .n. is

The figure is made of a uniform wire and represents a regular five pointed star. The resistance of a section EL is r 2 ohm. Find the resistance in ohm of the star across F and C. ( "sin"18^(@)=1/-3)

State three factors on which the resistance of a wire depends. Explain how does the resistance depend on the factors stated by you.

When the resistance of copper wire is 0.1 Omega and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14 xx 10^(-8) ohm xx m )

The resistance of galvanometer is g ohm and the range is 1 volt. The value of resistance used to convert it into a voltmeter of ragne 10 volt is:-
