Chapter 31 – Alternating Current - Physics
Rectified average current (Irav): during any whole number of cycles, the total charge that flows is same as if current were constant (Irav). - Diode (rectifier): device that conducts better in one direction than in the other. If ideal, R = 0 in one direction and R = ∞in other. full wave rectifier circuit average value of Іcos ωtІor Іsin ωtІ

Chapter 5 – Force and Motion I
physics.ucf.eduChapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.
Chapter 5 – Force and Motion I - Physics
physics.ucf.eduN mg (5.5) - Normal force: perpendicular force on a body from a surface against which the body presses. - Frictional force: force on a body when the body attempts to slide along a surface. It is parallel ... Chapter 5 – Force and Motion II - Opposes the relative motion of a body in a fluid.
Chapter 29 – Electromagnetic Induction
physics.ucf.eduFaraday’s Law of Induction: - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop. dt ε= − dΦB - Increasing flux ε< 0 ; Decreasing flux ε> 0 - Direction: curl fingers of right hand around A, if ε> 0 is in same direction of fingers (counter-clockwise), if ε< 0
