Capacitors and electrostatics
PHY 114
Abstract: The purpose of this experiment was to measure the electrostatic force between two objects as a function of their signs and electrical charges. This was done using many equipment’s such as a glass and rubber rod. In addition, investigate how capacitors store energy electrostatically in an electric field, share charges and discharge. This was done by using equipment’s like voltage follower, DVM, powered breadboard unit and a selection of capacitors. The capacitors used were .1 µf, 1.0 µf and an unknown. They were used to examine how energy was transferred and how much is transferred. After conducting the experiment and gathering the calculations. The results show that a .1 µf capacitor transferred .39 V charge. Then we transferred charge with 1.0 µf capacitor the voltage came out to be twice as much at .81 V. This make sense because the charge transferred from the first capacitor was stored in the memory. Therefore when more charge was transferred it was added to what was already there. In addition, the charge after transferring the unknown was 1.5 µF. lastly, through a set of graphs we determined that when a resistor is connected to a charged capacitor, the charge stored on the capacitor will flow out due to the charge converting to heat on the resister.
Objective: The objective of this lab was to measure the electrostatic force between two objects as a function of their signs and electrical charges. Also investigate capacitors and their properties.
Procedure:
For part A Rub a glass rod with a cloth. Touch the input and rub the glass rod back and forth along the input. Then, zero the meter by shorting and rub a rubber rod with the same cloth and transfer this charge to the input of voltage follower by touching the metal plug For part B connect the voltage follower input (with the 0.1 F capacitor) to the 5 V supply on the breadboard unit. Touch momentarily the same positive Minigrabber TM to
