An initially uncharged air-filled capacitor is connected to a 2.67 V2.67 V charging source. As a result, the capacitor acquires
6.39×10−5 C6.39×10−5 C of charge. Then, while the capacitor remains connected to the charging source, a sheet of dielectric material is inserted between its plates, completely filling the space. The dielectric constant ????κ of this substance is 6.03.6.03. Find the voltage VV across the capacitor and the charge ????fQf stored by it after the dielectric is inserted and the circuit has returned to a steady state.
It increases confidence because the more times you conduct the same experiment over and over should either prove your hypothesis right and wrong and eliminate any random occurrences that might affect your results.
