The antioxidant-promoting composition of the invention safely induces cellular antioxidant potential to achieve an overall net decrease in oxidative stress without the undesirable side-effects associated with the individual components of the antioxidant-promoting composition. Also disclosed is a method for reducing the undesirable side-effects of free radicals in a subject by administering to a subject in need of such antioxidants an effective amount of antioxidant-promoting composition of the invention.
Be sure not to hold the resistor terminals when measuring resistance, or else your hand-to-hand body resistance will influence the measurement!
Record this resistance value for future use. Build a one-battery, one-resistor circuit. A terminal strip is shown in the illustration, but any form of circuit construction is okay. Set your multimeter to the appropriate voltage range and measure voltage across the resistor as it is being powered by the battery.
Record this voltage value along with the resistance value previously measured. Set your multimeter to the highest current range available. Break the circuit and connect the ammeter within that break, so it becomes a part of the circuit, in series with the battery and resistor.
Select the best current range: If your multimeter is autoranging, of course, you need not bother with setting ranges. Record this current value along with the resistance and voltage values previously recorded. Compare this calculated figure with the measured figure for circuit current: Compare this calculated figure with the measured figure for circuit resistance: Compare this calculated figure with the measured figure for circuit voltage: There should be close agreement between all measured and all calculated figures.
Any differences in respective quantities of voltage, current, or resistance are most likely due to meter inaccuracies. These differences should be rather small, no more than several percent.
Some meters, of course, are more accurate than others! Substitute different resistors in the circuit and re-take all resistance, voltage, and current measurements.
Re-calculate these figures and check for agreement with the experimental data measured quantities. Also note the simple mathematical relationship between changes in resistor value and changes in circuit current.
Voltage should remain approximately the same for any resistor size inserted into the circuit, because it is the nature of a battery to maintain voltage at a constant level.Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow.
