Chapter 24 – Capacitance and Dielectrics

- Capacitance is a measurement of the ability of capacitor to store energy (V = U / q). Capacitors in Vacuum - Parallel Plate Capacitor: uniform electric field between the plates, charge uniformly distributed over opposite surfaces A Q E εo εo σ = = d A V Q C ab = =ε0 A Qd V E d o ab ε 1 = ⋅ = ε0 = 8.85 x 10-12 F/m

Chapter 5 – Force and Motion I

Chapter 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 29 – Electromagnetic Induction

Faraday’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

Sustainable Prepared by: Transportation Strategies

DC fast chargers have the charging cable and connector permanently affixed. Various designs of Level 2 EV supply equipment can attach to ground surfaces, walls, posts, poles, and ceilings. The majority of EV supply equipment being sold can charge one vehicle at a time but models are available that can connect with two to four vehicles at once.

Know a Battery’s State-of-Charge By Counting Coulombs

run time based on the battery’s state of charge (“SoC”) is of paramount importance. Some primary cells tend to have very flat discharge curves, such as those of the Lithium Thionyl Chloride cell, shown in Figure 2. This characteristic makes the remaining cell capacity very difficult to determine or predict. Figure 2.
