Aluminium is a trivalent element with atomic weight of 27 gm/mole and density of 2.7*103 kg/m3, with a mean free time between electronic collissions of 4*10-14s. Calculate the current that flows in a 10m long AL wire that has a 1 mm2 cross section area when a potential of 2 V is applied to the end of the wire.
The Power Consumption of a single-phase electric load fed from a 120 V source is represented by: P(t) = 100(1- e -t/10 ) KW where t is the unit of time in hours. Compute the energy consumed by the load over the period of 24 hours.

What bit pattern (after you remove the beginning and ending flags and any stuffed bits) will the receiver pass on for higher level processing?
Assuming that the current through and inductor is i l(t) = 10exp(-t/3). Find at what time this current dropped by 50percent of its initial value.
The resistance, inductance and capacitance of a parallel RLC circuit are 5 kO, 1.25 H and 8 nF, respectively. a- Calculate the roots of the characteristic equation that describe the the voltage response of the circuit. b- Will the response be overdam..
A 37.5-kVA, 6900-230V, 60Hz, single phase transformer is operating in the step down mode at rated load, rated voltage, and 0.68 power factor lagging. The equivalent resistance and reactance referred to the low side are 0.0224Ω and 0.0876Ω
The rotor of a 3phase, 5kw, 400v, 50Hz, slip ring indution motor is wound for 6 poles while its stator is wound for 4 poles. The approx average no load steady state speed when this motor is connected to 400v, 50Hz what is the supply
