... a conductor, its strength and the resistance offered, was directly proportional to the electric current produced, which later came to be known as the Ohm's Law. we can use these principals in literally hundreds of science fair experiments.
... work in relation to an electrical current. Given two of the values, students should be able to plug in values to Ohm's Law and solve for the third. ... How to Make soap out of guava leaf extract for a science investigatory project ...
Log in · ← And Now for a Little Perspective… Citizen Science Musings: Patrick Moore and the Rest of the Story → ... First is Ohm's law, E=IR. You rearrange this to get a result for resistance (that is R=E/I). You measure a voltage of 5 volts and an amperage of 1 amp across an unknown resistor. Using Ohm's law, the resistance must be positive or plus 5 ohms (R=E/I, R=5 V/ I A= 5 Ohms). Graphing the current and voltage would generate a straight line and the slope of ...
