A portion of a residential service to a home is depicted in given figure:
a. Determine the current through each parallel branch of the network.
b. Calculate the current drawn from the 120-V source. Will the 20-A circuit breaker trip?
c. What is the total resistance of the network?
d. Determine the power supplied by the 120-V source. How does it compare to the total power of the load?
If there are 500 atoms in the sample and assuming that from any state all possible downward transitions are equally probably, what is the total number of photons that will be emitted when all atoms return to the ground state
For the difference equation below, find the impulse response by first solving without any transforms. Assume sequence is zero-valued for n
(a) A Ge bar 0.1 cm long and 100 m2 in cross-sectional area is doped with 1×1017 cm-3 gallium. Find the current at 300 K with 10 V applied. (b) Upon a steady illumination uniform excess carriers are generated in the Ge bar.
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.
An elevator in a 20-story building is used to raise a 7200-N load 50 m. How much will it cost to raise the load if electricity costs $0.078/kWh?
A circuit is needed to display a 4-bit value on the LEDs of the logic designer. This value can come from two different sources. Design a circuit using four 2-to-1 multiplexers to select which of the two values to display on the LEDs.
A steam power plant with a power output of 150 MW consumes coal at a rate of 60 tons/h. If the heating value of the coal is 30,000 kJ/kg, determine the overall efficiency of this plant.
What is the resulting attenuation at 3.1 GHz? Use CAD to plot the insertion loss versus frequency.
Determine the current in a circuit consisting of a 1000-ohm resistor with a voltage of 50 volts DC across it. When using an ammeter, why do you place it in parallel with the circuit
The power dissipated in the resistor R0 is 89 W when connected to a 10V source. Find the total dissipated power if 3 resistors identical to R0 are connected in series to a 10V source.
In a circuit, there is a resister, a conductor and a capacitor connected to voltage source. R = 25 ohms, L = 20 milliH, and C = 50 microF. a) Find the total impedance of the network if the frequency is 60 Hz.
