Physics 1302 Exam 1 Review Professor Mini Das Ch. 19-22 Chapter 19 Electric Charges, Forces, and Fields 19.1 19.3 19.4 19.5 19.6 Chapter 20 20.1 20.2 20.3 20.5 20.6 Chapter 21 21.1 21.2 21.3 21.4 21.5 21.6 21.7 21.8 Chapter 22 22.1 22.2 22.3 22.4 22.5 22.6 22.7 Formulas And when to use them • Force of one charge onto another charge in a line or 2D shape • Force on a charge in a given electric field (sometimes need to set equal to mg if the opposing force is equal and opposite and you’re given the mass) • A charge (usually starting from rest) accelerated through a potential difference when a charge moves across a potential difference, its potential energy changes • A charge moving across parallel plate capacitor given energy used or potential difference between the plates • Electric field established by connecting battery to parallel plate capacitor (given voltage and separation of plates) • Two point charges separated by a certain distance with an electric field between the 2 charges • Asked for electric potential of a point charge • Because the corresponding change in potential energy for the charge: • Flux is the measure of electric field perpendicular to a surface, so its max is when the surface is up and down if the electric field is LR; if parallel electric field it =0; if given a surface and electric field or a closed surface with a bunch of charges, most likely use a flux equation (Φ) • current is the change in charge over time • Can also use to find the number of (protons/electrons) whichever charge they say it is because you can find q then divide that answer by the charge of the particle • Ohm’s law applies to questions involving circuits, potential, current, resistance, etc. • If asking about power power is work over time • C is capacitance • Fancy ҡ is dielectric constant; ke is the constant in the force equation • Remember for right hand rules: • V X B- V is pointer finger, B is middle finger, F is thumb • I X B- I is pointer finger, B is middle finger, F is thumb • N= number of loops in a solenoid • Prefixes!! • Nano- 10^-9 • Micro- 10^-6 • Milli- 10^-3 • Etc. 19.6 Chapter 20 20.2 Chapter 21 Chapter 22
