PHYS 105 1nd Edition Lecture 33Outline of Last Lecture I. ExamOutline of Current Lecture II. ResistorsIII. Electric power and energy IV. CapacitorV. Faraday’s law of InductionCurrent LectureI. Resistors- Important element in electric circuit - Can be connected in series or in parallel - Serieso Total resistance of equivalent circuit is the sum of resistance of al resistors - Parallelo Inverse of the equivalent resistance is given by the sum of the inverse resistance of all resistors II. Electric power and energy - Energy = Power x Time- Power = o IxVo I^2 x Ro V^2 / RIII. Capacitor- Sheet of parallel plates can be used to store electric charge - Capacitance C = Q/V [Amount of charge can be stores with a given amount of electric potential increase]- Unit of capacitance is Farad These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.IV. Faraday’s law of Induction- Varying magnetic field induces electric field- When electric current flow in the wire, it produces magnetic field - When electric wire is coiled together, the magnetic field is concentrated in the device o Called an inductor with symbol ‘L’o Unit of inductance is Henry
