- Write an expression for the output voltage of an ac source that has an amplitude of 12 V and a frequency of 200 Hz.arrow_forwardAn inductor and a resistor are connected in series across an AC generator, as shown in Figure CQ21.16. Immediately after the switch is closed, which of the following statements is true? (a) The current is V/R. (b) The voltage across the inductor is zero. (c) The current in the circuit is zero. (d) The voltage across the resistor is V. (e) The voltage across the inductor is half its maximum value.

- A transmission line that has a resistance per unit length of 4.50 104 /m is to be used to transmit 5.00 MW over 400 miles (6.44 105 m). The output voltage of the generator is 4.50 kV (rms). (a) What is the line loss if a transformer is used to step up the voltage to 500. kV (rms)? (b) What fraction of the input power is lost to the line under these Circumstances? (c) What difficulties would he encountered on attempting to transmit the 5.00 MW at the generator voltage of 4.50 kV (rms)?arrow_forwardAn AC generator with an rms emf of 15.0 V is connected in series with a 0.54-H inductor. The frequency of the source emf is 70.0 Hz. Draw a phasor diagram for this circuit, including the current, the potential difference across the inductor, and the source emf. Draw your diagram with the current phasor pointing toward the right along the horizontal axis.arrow_forward
