PHYSICS 202 Study Guide - Midterm Guide: Resistor, Inductance, Rlc Circuit
Document Summary
Indicate the direction of emf in the following cases: The emf induced in a circuit is proportional to the time rate of change of magnetic flux through the. Does not have to be real conducting circuit. The path/circuit does not have to be circular, or even planar nominal direction of . Change b emf produced by an induced e field. Reminder: magnetic field inside the solenoid (ch 28) Energy stored in an inductor is u= li2. This energy is stored in the form of magnetic field: energy density: ub = b2/ 0 (recall: ue= 0e2) Resistor: no energy stored, (all energy converted to heat) V=v- - v+ = - q/c, dq/dt =i. Rc e t /rc q(t)/c + r dq(t) dt = 0. Capacitor: energy stored uc= c( v)2 = q2/c. Current and voltages in a series rlc circuit. E and b are normal to each other.
