    SPACE - LAB - Q3 2 Capacitance

    Uploaded by

    Lawrence Carl
    The document describes a laboratory experiment on capacitance using a PHET simulation. The objectives are to determine capacitance with different dielectrics and connections of capacitors. Part A explores dielectrics, finding capacitance increases with higher dielectric constants. Part B examines capacitors in series, finding total capacitance decreases and voltages divide. Part C looks at parallel capacitors, finding voltages are equal and total capacitance increases. The document provides instructions and questions to guide the virtual experiment.
