A transformer has a primary voltage of Vp= 400 V and primary current of Ip=1.5 A. If the measured values of secondary voltage and secondary current are Vs= 195 V and Is= 2.9A, respectively a) calculate the efficiency of this transformer. b) write the type of the transformer(step-up or step-down) with its reason.
An inductor that has an inductance of 15.0 H and a resistance of 30.0 Q is connected across a 100-V battery. What is the rate of increase of the current at t = 0
A transformer is a device that takes an input voltage and produces an output voltage that can be either larger or smaller than the input voltage, depending on the transformer design. Although the voltage is changed by the transformer, energy is not, so the input power equals the output power. A particular transformer produces an output voltage that is 300 percent of the input voltage. What is the ratio of the output current to the input current?
