When the current i is flowing through a conductor, the drift velocity is v. If 2i current is flowed through the same metal but having double the area of cross-section, then the drift velocity will be

In a neon discharge tube 2.9×10^18 Ne+ ions move to the right each second while 1.2×10^18 electrons move to the left per second. Electron charge is 1.6×10^-19 C. The current in the discharge tube

62.5×10^18 electrons per second are flowing through a wire of area of cross-section 0.1 m^2, the value of current flowing will be

Which of the following characteristics of electrons determines the current in a conductor.

A current I is passing through a wire having two sections P and Q of uniform diameters d and d/2 respectively. If the mean drift velocity of electrons in sections P and Q is denoted by vPand vQ respectively, then

A beam contains 2 × 10^8 doubly charged positive ions per cubic centimeter, all of which are moving with a speed of 10^5m/s. The current density is

A cylindrical metal wire of length / and cross-sectional area S, has resistance R, conductance G, conductivity o and resistivity p. Which one of the following expressions for σ is valid

An electric cell of e.m.f. E is connected across a copper wire of diameter d and length 1. The drift velocity of electrons in the wire is vd. If the length of the wire is changed to 2L, the new drift velocity of electrons in the copper wire will be
