Consider the following function of t, f(t)=1/a[u(t-T0)-u(t-T0-a)]. Here both T0 and a are positive numbers. If you pick some value for T0 and a you discover that you have a rectangular pulse starting at T0 having width a and height 1/a. Obtain the Laplace transform of this pulse by direct integration. If you let a -> 0 you obtain a unit impulse. Let a -> 0 in the expression you obtained for the laplace transform of the pulse to obtain laplace transform of the shifted unit impulse.
A standard 12-V car battery has an ampere-hour rating of of 30 Ah, whereas a heavy-duty battery has a rating of 51 Ah. the ratio of available energy is 1.7 ratio. Find the percentage increase in available current for starting
When placed in series a coil and capacitor resonate at a fequency of 2251Hz and when placed in parallel they resonate at a frequency of 2228Hz. At parallel resonance it is also found that a current of 0.005A flows from the supply when the supply i..
Assuming that solar energy is used to charge a storage battery which then in turn is to power a lamp of 40W. Solar cell obtains power at the rate of 100milliwatts per square centimeter, and the sunlight time is 12 hours.
1-If the voltage is 106 V cos(84 rad/s t + 46°) and the current is 9 A cos(84 rad/s t + 72°), what is the frequency of the instantaneous power. 2- If the voltage is 101 V cos(47 rad/s t + 11°) and the current is 16 A cos(47 rad/s t + 67°).
A 100μF capacitance is initially charged to 1000 V. At t1=0, it is connected to a 1kΩ resistance. At what time t2 has 50 percent of the initial energy stored in the capacitance been dissipated in the resistance
