Hello,

I did a lab the other day, I have put in all my data, I just need help with the six highlighted areas in green on the second document. Thanks do much xoxoxo

The capacitance is a measure of a device's ability to store charge. Capacitors are passive electronic devices which have fixed values of capacitance and negligible resistance. The capacitance, C, is the charge stored in the device, Q, divided by the voltage across the device, V: c= 2 The SI unit of capacitance is the farad, 1 Farad = 1 Coulomb/1 Volt. Capacitance can also be calculated from the geometry of the device. For most practical devices, the capacitor consists of plates which are thin sheets of metal separated by a dielectric (insulating) material. For this reason, the schematic symbol of a capacitor has two vertical lines a small distance apart (representing the capacitor plates) connected to two lines representing the connecting wires as shown below. Sometimes the sheets are rolled up in a spiral to increase the overall area while keeping the device compact, leading to cylindrical shaped capacitors. A. Series Capacitors: Connecting capacitors in series means the components are connected at a single point, end to end as shown below in Fig la. 5the ) twoled conne Battery Battery Fig 1. (a) Capacitors in series (b) Capacitors in parallel The total capacitance for n capacitors in series is shown to be: (1) B. Parallel Capacitors Connecting capacitors in parallel means the components wired "across" each other as they are connected to a source as shown above in Fig 1b. Because conductors, i.e., wires, are equipotential, the capacitors have the same voltage of the source since they are connected to it through a conductor. In this lab, no source is necessary to measure capacitance of parallel capacitors given by:Lab Manual PHY-1570 (College Physics II) Summer - 2023 C , = C, + C 2 + C , +... + Cr (2) Capacitance Values measured in isolation with DMM (individual): C1 = Purple Cap C2 = Dark Blue Cap C3 = Light Blue Cap Q : CV . 10 - 3 ( converted to millicoulombs ) Series connection Parallel Connection Capacitance (m Voltage (Volts Charge (mc) Capacitance (mF) Voltage (Volts) Charge (mC) C1 = 99. 3 nff V1 = 210my Q1 = 2. 09 x19 |CI = 99. 3 nF V1 = 2.
