Printed Name_____________________________ Section__________________________ PHYS-1200 PHYSICS II F 2010 Lecture 2 Worksheet: Capacitance 1. Charge flow in circuits A capacitor and light bulb are wired in series as shown on the right so that charge flowing into the capacitor must flow through the light bulb. Sketch the charge on the capacitor as a function of time after the switch is closed. Sketch the current as a function of time after the switch is closed. The light bulb serves as an indicator of current flow. 2. Potential in circuits A capacitor and light bulb are wired in series as shown on the right so that charge flowing into the capacitor must flow through the light bulb. Sketch the potential difference across the capacitor as a function of time after the switch is closed.

Unformatted text preview: 1 Q t i t V t Printed Name_____________________________ Section__________________________ 3. Energy storage in capacitors If the switch is held so that the battery is across the capacitor, then the capacitor fully charges to V B . Sketch the charge on the capacitor as a function of time when the switch is pushed down to short out the capacitor/bulb circuit. Sketch the potential difference across the capacitor as a function of time after the switch is pushed down. Sketch the current in through the bulb as a function of time after the switch is pushed down. Sketch the brightness of the bulb as a function of time after the switch is pushed down. 2 V t Q t i t i t...
