Physics coursework Hypothesis-I predict that the resistance of the resistors can be found by dividing the voltage by the current through the resistor. It can be found by finding the gradient of the best-fit line on the graph of voltage against current. This will happen because the voltage and current are proportional so voltage will equal constant current. The constant term is the resistance so the resistance is voltage divided by current. The gradient on the graph can be formed by dividing the unit on the y-axis by the unit on the x-axis which will be voltage divided by current or on the filament lamp graph it will be current divided by voltage. The gradient will depend on the resistance of the resistors. Ohm's law will be followed if the graph is a straight line through the origin, so this can be used to prove Ohm's law is valid. Background Information- Current is the...
