Current Divider: What is it? Formula, Rule & Examples

Webyes. you multiply both sides of resistance formula R=ρL/A with A, and formula becomes RA=ρL, then you divide both sides with ρ, and formula becomes RA/ρ=L. same principle is valid for any kind of formulas rearrangements I think that Kirchhoff's junction rule is a bit unclear about the fact that while the … A voltage is necessary for a current to flow. An electric current is the movement of … WebTherefore, we can apply Ohm’s Law (I = V/R) to the current through the resistor because we know the voltage (V) across the resistor and the resistance (R) of that resistor. All terms (V, I, R) apply to the same two points in the circuit and to that resistor, so we can use Ohm’s law formula with no reservation: I = V R I = V R WebThe voltage difference we expected was 3.3 V (power supply) - 3 V (LED) = 0.3 V remaining for the resistor. That's a 270 Ω resistor then 0.3 V/ 270 Ω = 1.1 mA. The 3.3 mA is the same thing, but now with the 2.4 V you measured, so the 3 V we presumed wasn't quite right. Do the calculation like I just did. – stevenvh Jul 19, 2012 at 15:42 inbuilt images in matlab

WebWhat is the current in the resistor? Using Ohm's Law, i = v/R gives us i = (A sin wt) / R. So when the voltage is a sinusoid, the current is a sinusoid, too. In general, if you define either v or i to be sinusoidal, the other will follow along and be sinusoidal, too. In a resistor, the sinusoidal i and v are lined up with each other in time.
