PART ONE:
If an electric circuit contains only an ordinary resistor, all the work done by the electric current appears as:
A) light
B) rotary motion
C) chemical action
D) heat
PART TWO:
Two 10.0 ohm resistors are connected in parallel, and this combination is connected in series with a third 10.0 ohm resistor. The resistance of this network is

Design an active low pass filter with a cutoff of 10kHz or more by more than 30db and have the pass band gain positive that does not deviate from 20db by more than 3 db. The pass band frequncy need is 800Hz and below.
A six-cylinder, four-stroke, 4.5-L compression-ignition engine operates on the ideal diesel cycle with a compression ratio of 17. The air is at 95 kPa and 55°C at the beginning of the compression process and the engine speed is 2000 rpm.
Design a low pass active filter such that its roll off attenuates frequency components a 10kHz or more by more than 30 db. This means that the magnitude of the transfer function (in db) at frequency 10kHz should be -30db or less
Derive equations for the capacitance, and resistance across the dielectric of a coaxial line of inner conductor radius a, and outer conductor radius b, and permittivity ε.
The average intensity of sunlight reaching the earth is 1390W/m2. A charge of 2.38 x 10-8 C isplaced in the path of this electromagnetic wave. What is the magnitude of the maximum electric force that the charge experiences
you are an electrician on the job. you have been given a multimeter that has the following AC voltage ranges: 30,60,and 150. the meter states that it has a resistance of 5000ohm/v. you need to be able to measure a voltage of 277 volts.
Write a program to blink the last 3 digits of your social security number on 3 bits of Port B. For example if the last 3 digits are 654 then bit 2 of Port B should blink 6 times, bit 1 should blink 5 times and bit zero 4 times.
Suppose that the type of key in a hashing application you are implementing is String. Design, implement, and test a hash function that converts a key to a hash value. Assume that the size of the hash table is a prime number.
An open-circuited 50 Ohm microstrip transmission line is used in a microwave amplifier circuit to provide a capacitance of 3.2 pF at 2.3 GHz. (a) Find the appropriate electrical length of the line and (b) Find the lumped element values of the open..
Figure 1 shows the network diagram of a 132kV power system. The network has three buses and two generating units. The loads of (l.O+jO.35) pu and (3.2+J1.2) pu are connected at bus 2 and 3 respectively. The generator connected at bus 2 injects 1.2..
Generate a new random variable X with pdf fX. Specifically, we want to generate a Gaussian random variable and relationship between Rayleigh and Gaussian distributions.
The nameplate on a 460-V 50 hp 60 Hz four pole motor indicatesthat the speed at rated load is 1760 r/min. assume the motor to beat operating load. a) What is the slip of the rotor b)what is the frequency of the rotor currents
