Presentation Summary : The convenience and safety of household electricity depend on how the electric circuits in your home are designed. This is electromagnetic induction. Electric charge is always conserved. ). P6.1 with e(t) = 12sin(120 π t) V. When S 1 and S 2 are open, i leads e by 30 ° . P6.4 6.5) Consider the circuit in Fig. In a circuit, it is important to be able to turn it off and on. 6.6 4) The series RLC circuit (Fig. No enrollment or registration. It refers to… Fig. The collection or flow of electrons in the form of an electric charge What is Electric charge can either be positive or negative. Find the value of R such that the power in R is maximized ? When S 1 is closed and S 2 is open, i lags e by 30 ° . If the circuit is lossless (there is no resistance) dt dU = Li dt di + Cv c dt dv c = 0 (6.2) i = -C dt dv c ⇒ dt di = -C 2 c 2 dt vd ⇒ LC 2 c 2 dt vd + v c = 0 (6.3) ⇒ v c (t) = Vcos( ω t) (6.4) and i(t) = V ω Csin( ω t) (6.5) where LC 1 =ω (6.6) Fig. We don't offer credit or certification for using OCW. 6.4 2) Inductive load : (Fig. • Like poles repel and opposite poles attract. Magnets •Materials that attract other metals •Three classes: natural, artificial and electromagnets •Permanent or Temporary •CRITICAL to electric systems: – Generation of electricity – Operation of motors – Operation of relays. The motion of a charge is affected by its interaction with the electric field and, for a moving charge, the magnetic field. I made this for my group to gather info for a ppt to present in Professor Davidian's class. View elec_mag.ppt from CHEM 101 at North South University. A coil of wire carrying an electric current can create a magnetic field! The impedance of the capacitor ωC 1 == m m I V z I m , V m : amplitude of i and e, respectively. When S 1 and S 2 are closed, i has amplitude 0.5A. If so, what maximum resistance is required? Find i R (t), i L (t), i C (t), V(t), the storage energy of the capacitor, the storage energy of the inductor, and the total storage energy (R in Ω , L in mH, C in µ F). Note: Your 9 digit Mobile Number without +971. H6.2 where e = 100sin(1000t). . Electromagnetism: Electric and Magnetic Field Henry Sergio Jr. Find the value of R such that the power in R is maximized ? Electricity and Magnetism – how are they related? With more than 2,400 courses available, OCW is delivering on the promise of open sharing of knowledge.
