Electrical Circuits and Electric Currents

Heat is generated at a steady rate of 100 W due to resistance heating in a long wire (length = 5 m, diameter = 2 mm). This wire is wrapped with an insulation of thickness 1 mm that has a thermal condu

A tungsten wire used in a constant current hot wire anemometer has the following parameters : Resistance at 0° C is 10Ω, Surface area is 10-4 m2, Linear temperature coefficient of resistance of t

A piece of copper wire has twice the radius of a piece of steel wire. The Young s modulus for steel is twice that for the copper. One end of the copper wire is joined to one end of the steel wire so t

The first order liquid phase reaction A ---> P is conducted isothermally in a plug flow reactor of 5 liter volume. The inlet volumetric flow rate is 1 liter/min and the inlet concentration of A is 2 m

Flow of electrons in a wire is known as

The ratio Nf/Nd is known as shape factor, where Nf is the number of flow lines and Nd is the number of equipotential drops. Flow net is always drawn with a constant b/a ratio, where b and a are distan

If length of wire is 1 m and cross-sectional area 5×10-5 m², when wire streched through 1 mm by a force of 10,000 N. Young's modulus of wire would be
