Suppose that, in designing an electrical generator, we need to produce a voltage of 120V by moving a straight conductor through a uniform magnetic field of 0.5 T at a speed of 30 m/s. The conductor, its motion, and is the required length of the conductor? It turns out that in generator design, a conductor of this length is impractical, and we must use N conductors of length 0.1 m. However, by connecting the conductors in series, we can obtain the required 120 V. What is the number N of conductors needed?
A circuit consist of two impedance,Z1=50/_45 ohms and Z2=25/_30 ohms, connected in parallel. They are supplied by a source whose voltage is V=50/_0 volts. Determined follows 1. the current drwan by each impedance
