A step-up transformer has 23 turns on the primary coil and 800 turns on the secondary coil. If this transformer is to produce an output of 5000V with a 14-mA current, what input current and voltage are needed? Input current = .49 A V = ? kV
Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...
