A ceramic capacitor has a value of C=10,000 pF. The capacitor consists of a dielectric disc between two paralell metal disc plates. The dielectric disc has a relative permittivity of 40. The diameter of the disc plates is 1 cm. The voltage across the plates is 100 V. Find the charge density on the inside surface of a disc plate in Columbs per cubic meter. Round off your answer to one decimal.
A synthetic jet is used for flow control in an airplane wing. The mechanism that creates the jet stream is a piston system driven by an electric motor. The velocity at the jet exit can be expressed as a harmonic function depending on the movement period of the piston. In order to determine the velocity function and frequency structure, measurement is made with a hot wire anemometer at the jet exit. A single wire probe is used in the experiments. An A/D card with an input voltage range of ∓5 V is used while transferring the data to be obtained from the hot wire anemometer to the computer. At least how many bits of card should be used for 2.5 mV resolution?
