Imagine that you would like to design a parallel plate capacitor that could store 1 J of electrical energy in the electric field between its plates when connected to a 1.5 V battery.
Imagine that you can arrange things so that the plates can be separated by a distance d as small as 0.5 mm.
(Hint argue that the electric field strength between the plates is E approximately equal to V/d, where V is th potental difference between the plates).
A 100 Watt heater is used to melt 2 kg of solid ice at -10oC to liquid at +5oC at a constant pressure of 150 kPa. a) Find the change in the total volume of the water.
Using Logisim, implement a 3-8 Decoder, both with gate level components and a Decoder component. Use input pins to control the select line inputs, and LEDs for the output display.
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.
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.

A jar contains one blue balls, two red balls, and three green balls. Consider the following experiment We pick on ball randomly from the jar, record the color, and put it back. We then pick a ball randomly for one more time and record the color.
Find the electrostatic potential on the axis of a uniformly charged cylindrical surface of radius ro and height h. The surface charge density is ρs.
How does ambient temperature affect the forward bias voltage of a diode. For some significant enough increase in temperature, how will the voltage across the diode terminals be affected
you have a bandwidth of 10 mhz per direction in a single-cell system and want to deploy a wireless telephone system.
