Capacitor investigation report Eleanor hood Aim: the aim of this investigation is to study capacitors charging and discharging. A capacitor is charged by placing it in a circuit with a resistor and a power source. When electrons flow round the circuit they can not cross the gap the capacator makes. A negative charge builds up on this side of the capacitor whilst on the other a positive charge because of this. A potential difference across the gap now occurs causing the charging to slow down. When the voltage across the gap is equal to the voltage of the power supply there is no current as there is no voltage difference/ potential difference and the capacator is now fully charged. A capacitor can then be used in a circuit on its own with out a power source the charge of the capacitor gradually leaves it, and is discharging. Method: In This experiment we...
