RL Circuits

RL Circuits. Physics 102 Professor Lee Carkner Lecture 21. PAL #21 Generator. To produce 12 amps in a 15 ohm wire you need an emf of e = IR = (12)(15) = 180 V Set 180 V equal to the max emf e = NBA w w = e /NBA = 180/(1)(2)(1) = 90 rad/s If w = 90 rad/s, we can find f = w /2 p

EMF induced

EMF induced. The Peak emf induced: rms value of induced emf is:. While Peak Flux is: ? m = LXB m sin ? t. Change in Flux. The change in the flux linkage can be brought about in a variety of ways: coil may be static and unmoving but the flux linking the same may change with time
