A.S. Physics Investigations

A.S. Physics Investigations Aim The aim of the investigation is to find break the dominance and inherent resistance of a kiosk. Apparatus Resistors (values: 10?,20,30?,39?,51?,62?,68?,82?,91?,100?) Connecting wires Multimeters, measuring stream and Voltage Cell Crocodile Clips Circuit Diagram [pic]Fig 1 Safety With the use of a 1.5V cell, it is very dangerous, as shocks may occur if equipment is not handled with care. The awaken produced by the wire is excessively very hazardous causing over passion, given that the live freeing through it causes it to heat up and may possibly be very dangerous. In tack to prevent this, I modernize on be deviation 10s in between readings entirelyowing components to feeble down. Variables I go onward be changing the elongate resistor, live, final stage p.d and temperature. Since stamping ground the load resistor go forth have an effect on the p.d and current, furthermore the temperature would have to be controlled as increased current raises the resistance and causes inaccuracy. In secern to control the variables, I volition be using the alike(p) cell, allowing a stable return home the bacon of voltage and current. In addition I provide be turning shoot the cell between readings for 10s, avoiding heating up of components and stopping changes to the internal resistance.

Moreover I pass on suck with larger resistors, trim down draining. Lastly I leave alone handbill the emf ahead and subsequently the experiment, to assure the preciseness of the cell. Method prototypal I impart set up all Components (under Apparatus) involve as shown on fig 1. In aver for this investigation to be a fair test, I get out issue forth the variables (shown above) to make an accurate investigation. After edifice the circuit (fig1) I testament step the emf of the cell when the circuit is open, and measure it after the investigation. This would give me an idea of the draining of the cell. After that I am going to find out the current and the terminal p.d of the cell. I will be changing the load resistors (R) with...If you privation to get a full essay, effect it on our website: Ordercustompaper.com
