A battery of three cells in series ,each of e.m.f 2volts and internal resistance 0.5 ohms is connected to a 2 ohms resistor in series with a parallel combination of two 3 ohms resistors draw the circuit diagram and calculate
A. The effective external resistance
B. The current in the circuit
C. The lost volts in the battery
D. The current in one of the 3 ohms resistors
wht it is advantage fir the amature to be rotate in radial magnetic field rather than a uniform one?
i. DC value
ii. RMS value
iii. Period of the voltage signal
Floating in front of you there is a long, horizontal wire which carries a 3.50A current from East to West. At the same altitude as the wire and 0.50m from it, there is an electron which, at this moment, is also moving from East to West. The electron is between you and the wire. The kinetic energy of the electron is 4.56·10-19J. What is the size and direction of the force on the electron? Your answer should be some number of Newtons in a direction chosen from { North, South, East, West, Up, Down }.
Determine the Z parameters of the network shown below and check the symmetry and reciprocity of the network. Also find the h parameters of the network.
