... current will increase proportionally until the experiments end. Theory: My theory is that as we give energy the electrons can move around more and flow around the circuit. There is also a silicon semiconductor in the thermistor, which determines the amount of current to pass through the circuit. Method: Once you have fully set up the experiment following the circuit diagram then you need to put the lit Bunsen burner under the tripod with the gauze and beaker of water. The Bunsen should be set with the collar half open to allow a slow but steady source of heat, which allows enough time to take each result. The temperature will now increase on the thermometer and you should take the readings of the current and voltage every five degrees to allow a large set of accurate results, and then stop once you reach 95º, to prevent the water from boiling over. In order to make ...
