Use the exact values you enter to make later calculations Part I: Data Record your data in the table using the same number of decimal places provided to you by the simulation. Please do not include units in your answers Part II: Data Record your data in the table using the same number of decimal places provided to you by the simulation. Please do not include units in your answers. Part III: Data Record your data in the table using the same number of decimal places provided to you by the simulation. Please do not include units in your answers With the voltage set at a constant value, such as 10 V, the current as the resistance is increased. Current is inversely related to resistance, so, for a given voltage, the current decreases as resistance increases. (I = V/R) With the resistance set at a constant value, such as 100 立, the current as the voltage is increased. Current is proportional to voltage for a given resistance, so the current increases when voltage increases. (I = V/R) The current through a resistor is mA. To the nearest volt, what is the potential difference across the resistor? The voltage across a 立 resistor is V. What is the current, in mA, through the resistor? An electron with electric charge of 1.6 10-19 C falls through a potential difference of 40 kV in the vacuum of an X-ray tube. What is the kinetic energy of the electron, assuming it started from rest and that there is no loss of energy to friction? (Note: 1 volt = 1 joule/coulomb.)
