Document Summary
The current in a lr circuit is given by i. If the wire loop has a re- sistance of 0. 067 , what is the rms current induced in the loop in amps? (1) 1,390 (2) 330 (3) 173 (4) 12,500 (5) 560. , which includes a factor of 1/ 2 to convert from peak to rms. The induced emf is given by faraday"s law as ing the derivative, and using = 2 f, we get. 2n r fb values given, we get and. Phy2049 fall 2007: a series rlc circuit is driven by an ac emf source of a fixed frequency. In order to make this circuit more inductive you need to decrease: (1) its natural frequency (2) its resistance (3) its inductance (4) its capacitance (5) the amplitude of the emf. The electrical supply is 120 v (rms) at 60. 0 hz; the lightbulb is rated at 1. 0 kw for this voltage.
