a new type of battery delivers 10W of power for 8hr without voltageor current fluctuation. after 8 hr without voltage or currentfluctuation. After8 hr however the power output drops linearly from10 W to 0 in only 5 min.
a. what is the energy storage capacity of the battery?
b. how much energy is delieverd during the last 5 min of the discharge cycle?
1-mH inductor carries a current: i(t)=50*t^2*exp(-2*t) inunit of mA. Determine the voltage, power, and energy of the inductor as a function of time.
A current filament carrying I in the -az direction lies along the entire positive z. At the origin, it connects to a conducting sheet that forms in xy plane. a) Find k in the conducting sheet.
determine the most cost-effective implementation by;selecting cables sizes and supply voltages and appropriate insulation. Assume copper wire is 3x as expensive as auminum wire and every AWG size increase corresponds to a 1.5x increase inwire pric..
a) Determine if the following expression is valid by using a truth table and by using algebraic manipulation: X1X3' + X2X3 + X2'X3' = ( X1 + X2' +X3)(X1 + X2 + X3')(X1' + X2 + X3) b) Use algebraic manipulation to show if x'(y' + z') = x'y' +x'z'
An aluminum casting that has a mass of 10 kg sits on a steel surface. How much force will be necessary to get it to start sliding. The static coefficient of friction (mu) for aluminum on steel is 0.61.
I have a 3.6V battery, a shottky diode with a voltage drop of 0.22V, and an LED rated at 3V and 100mA. How much resistance will I need. Do i subtract battery voltage - LED voltage and divide by current desired
a- The adjustability of the potentiometer can be used to obtain an adjustable output voltage b- Both power supplies must be used so that the adjustable voltage can have both positive and negative values
An inventor claims to have perfected an engine that wil produce power from energy transferred as heat from a 1000K flame. Energy wil be rejected as heat to the ground at 290 K. A 75 percent energy conversion efficiency is claimed.
A causal discrete LTI system is described by y(n)-3/4 y(n-1)+1/8 y(n-2)=x(n) where x(n) is the input and y(n) is the output Find the response of the system if x(n) =u(n)
A circuit must detect a 01 sequence. The sequence sets z = 1, which is reset only by a 00 sequence. For all other cases, z = 0. For example, for input sequence as follows, the corresponding output sequence would be: x = 010100100
An AAC is composed of 37 strands, each having a diameter of 0.333cm. Calculate the DC resistance in ohms per km at 75oC. Assume that the increase in resistance due to spiralling is 2%.
Plot the signal x(n) 0
