A double layer carbon capacitor consists of an anode and cathode of 1 g each of carbon cloth (S.S.A. = 2500 m2 g-1), the electrolyte being sulphuric acid. With reference to [3] make and justify an estimate of the capacitance of the cell.
Calculate the angular displacement between the rotor stacks. Determine the frequency of phase currents required to achieve a rotor speed of900r/min.
mesh analysis involves writing and solving a number of simultaneous equations. The number of equations is equal to the number of independent loops in the circuit. Each equation is derived from the application of KVL around the loop.
Instantaneous voltage and current of capacitor, The current flowing through a 5 F capacitor is i=3e^-2t. What is the voltage as a function of time, if the initial voltage is zero?
1) Calculate w in radians per second for each of the following: a. f = 30 Hz b. Period = 20 ms 2) Determine the rms values for each of the following: a. v = 100 sin wt V b. i = 8 sin 377t A
A negative charge of 2.0 micro coulombs is held at a distance of 0.30 m from a negative charge of 1.2 micro coulombs. Find the electrical force on the second charge due to the first charge, giving magnitude and direction.
specify the parameters Rin, Avo, and Ro of an amplifier that is to be connected between a 100k ohm source and a 2k ohm load and is required to meet the following specifications: A. No more than 10% of the signal strength is lost in the connection t..
Problem: This semester you will realize a Moore finite state machine for implementing the tail lights of a prototype car using four different design tools:
Electrons in solids have negative potiental energies with energy of a free electron (this means that these electrons needs to gain energy to liberate themselves from the solids ).
An uncharged capacitor and resistor are connected in series with a 12V source and switch. What is the voltage across the capacitor after the switch is closed and the capacitor is fully charged
A zener regulator circuit has a load resistance that varies between 470 ohms and 2700 ohms. The circuit uses a 10V zener diode, Rs = 330 ohms, and the source voltage is 24V. The zener resistance is 10 ohms and the zener test current (Izm) is 28mA.
describe the relationship between peak current peak-to-peak current and rms current. include in the discussion which
When using current mirrors as current amplifiers, a dc current source is often included on both the input side and the output side of the current mirror. What is the purpose of these dc current sources
