Internal resistance of the cell 0.8 ohms and the terminal voltage is 1.75V at a load of 500mA. what is the open- circuit voltage.
power supply has isolated +- 15V and +-6V outputs,what is the maximum positive voltage and maximum negative voltage that can be output from power supply.
BJT Circuit Configurations Compare the input and output impedance for each configuration. Compare the voltage gain and current gain for each configuration.
A 50HP single phase motor operates from a 480V, 60HZ supply. When delivering full rated power the motor efficiency is 89% and the power factor is 0.78 lagging. Determine the full load current.(Hint: 746W=1HP)
Modify the state diagram branching conditions in the diagrams below as needed to ensure the sum and exclusion rules are obeyed in each case.
Two metal plates with an area of 4 cm2 and separation distance of 0.01 cm are used to form a capacitance transducer. If the material between the two plates has a dielectric constant of 2.5 and the dielectric constant of free space is 8.85 pF/m
A transmitter operates with a carrier frequency of 2.0 MHz. It is amplitude modulated by two tones with frequencies of 1300 and 2300Hz. What frequencies are present in the output signal
(a) How many atoms are there in the unit cell characterizing the Si lattice (b) Verify that there are 4.994 X 1022 atoms/cm' in the Si lattice at room temperature. (c) Determine the eenter-to-center distance between nearest neighbors in the Si lattic..
2.25 kg of a fluid having a volume of 0.1 m^3 are contained in a cylinder at constant pressure of 7 bar. Heat energy is supplied to the fluid until the volume becomes 0.2 m^3. If the initial and final specific enthalpies of the fluid are 210 kj/kg..
Frequently, the output of transducers are much smaller than what an A/D converter expects on its input. That would require an amplifier to match it. Sometimes the output does not start at 0V. Usually the minimum reference input voltage of an A/D
AC Analysis Gain at Midband (with bypass capacitor in circuit) Connect the bypass capacitor using the switch.
Which sample produces greater Hall voltage: long and narrow or short and wide Thickness (d) is same in both the cases. With little explanations please. 1) If the concentration of scattering centers increase in the semiconductor, would it increase o..
How many voice channels are carried by a E1 transmission given 8 kHz sampling and 8 bit words? Why is an end of frame marker always required in a digital telephony system?
The voltage V across a semi conductor in a computer is given by V= aI+BI^2, where I is the current (in A). If a 24 V battery is conducted across the semi conductor, find the current if a=4 ohms and B= 0.5 ohms/A.
