A silver wire of radius 0.1 cm carries a current of 2A. If the charge density in silver is 5.86xx10^(28)m^(-3) , then the drif velocity is

A house is fitted with seven tubelights of rating 220 V, 40 W each , two bulbs of rating 220 V, 60 W each, five fans each drawing a current of 0.4 A at 220 V , and a heater of resistance 48.4 Omega . The main line power supplied to the house is at 220 V . Calculate the bill for the month of january if tubelights and bulbs are used for 6 h daily, fans for 1 h daily , and heater for 10 h daily. The electricity is to cost Rs. 2 per unit.

A current of 1.8 A flows through a wire of cross-sectional area 0.5 mm^(2) ? Find the current density in the wire. If the number density of conduction electrons in the wire is 8.8 xx 10^(28) m^(-3) , find the drift speed of electrons.

An air cored solenoid of length 50 cm and area of cross section 28 m^(2) has 200 turns and carries a current of 5.0 A. On switching off, the current decreases to across the ends of the solenoid. Find flux and emf induced if time is equal to 1.0 ms.
