WebFind the value of an inductance which should be connected in series with a capacitor of 5μF, a resistance of 10Ω and an ac source of 50 Hz so that the power factor of the circuit is unity. Ans: $ \displaystyle \frac{20}{\pi^2} $ Q:9. A voltage of 10V and frequency 1000 Hz is applied to a 0.1μF capacitor in series with a resistor of 500 Ω. Many different power frequencies were used in the 19th century. Very early isolated AC generating schemes used arbitrary frequencies based on convenience for steam engine, water turbine, and electrical generator design. Frequencies between 16+2⁄3 Hz and 133+1⁄3 Hz were used on different systems. For example, the city of Coventry, England, in 1895 had a unique 87 H…
WebFeb 8, 2024 · The number of cycles completed per second by an alternating quantity is known as frequency and is denoted by f. In SI system, the frequency is expressed in hertz (pronounced as hurts). One hertz (or Hz) is equal to one cycle per second. The number of cycles completed per second = f.
