A parallel plate capacitor has an area of 5.00 cm 2 and a capacitance of 3.50 pF. The capacitor is connected to a 12.0 V battery. After the capacitor is completely charged up, the battery is removed a. What must be the separation of the plates, and how much energy is stored in the electric field between the plates? b. If a sheet of Mica with εr=3.5 is placed between the plates, how will the voltage across the plates and the charge density on the plates change? c. If the sheet of Mica has an area of 3.00 cm 2 so that it does not cover the whole area of the plates, what would be the effective capacitance of this arrangement? d. If the Mica sheet is removed and the plates are moved 1.00 mm farther from each other, what will be the voltage between the plates, and how much work will it take to move the plates apart?
If an amplifier working with ±5V DC power supplies, requires a minimum output voltage of 3V across a load resistance of 100 ohms, calculate the minimum current to be drawn from the power supply, if the efficiency of the amplifier is 35%.
Suppose the circuit parameters in a series RLC circuit are: L = 1.0 µH, C = 10.0 nF, R = 100Ω, and the source voltage is 220 V. Determine the resonant frequency of the circuit and the amplitude of the current at resonance.
you are newly hired junior electrical engineer and assigned to a job site in a high rise condominium project. your main concern is to install electrical fixtures in each of the 5 rooms in the 5th floor you have 3 electricians waiting for your orders. What would you advise to your electricians about the project concerning there safety, equipment and tools to be used and strategy to finish the project as possible.
