Investigating the Effect of resistor on a Capacitor Circuit Method We will hatful up the following circuit. We will measure the capacitor pd. (Vc) with the cell connected. thus we will remove the cell and connect halt A to point B, at the same moment starting a stopwatch. We will translate the length of beat (t) for the Vc to decay to 3.75 Volts. We intend to repeat this procedure ingestion different resistors. IMAGE Resistance (kW) Time (s) 33 33 68 72 100 97 150 153 330 320 680 584 Conclusion From the graph we can distinctly see that the time taken for the capacitor to dis stimulate is directly relative to the resistance. This is because the graph shows a definite straight line going done or near most of the points. This way that the luxuriouslyer resistor you use the longer it will take for the capacitor to discharge. The experiment has therefore turn out the prediction correct i.e. the resistance should be d irectly proportionate to the time taken for the capacitor to de-charge. This can be explained by the following Capacitors strain electrical charge. When current is passing through the circuit the capacitor charges up as the current cant jump between the gap of the two plates only when charge is held there because of the force of the opposite poles. This means that to a greater extent and more electricity is stored until it reaches its full capacity. But when the circuit is broken the capacitor de-charges relinquish electricity through the circuit. The resistor slows down the current causing congestion and means that the capacitor has to de-charge slower because only a limited amount of charge can travel through a circuit with a high resistance at any one given time. Evaluation The method was a good way of carrying out the experiment as it was sooner easy to conduct once the circuit was connected, the results seem
