Bookmark or Share- When to use P=I^2R, P=VI, P=V^2/R? - Physics ForumsThe formula P=I^2R should be used when you know the current (I) and resistance (R) in a circuit and want to calculate the power (P) dissipated in that circuit. This formula is commonly used in Ohm's Law calculations.
- I understanding the formula Power loss= I^2 R - Physics ForumsIn summary: As you can see the square comes from Olm's law.In summary, the power loss in a circuit is given by I^2R, where I is the current and R is the resistance. This equation shows that if the current is doubled, the power loss will be 4 times greater.
- What is B = (mu * l)/(2pi*r) used for? - Physics ForumsIn summary, the equation B=(mu*l)/(2*pI*r) is used to find the magnetic field due to a straight wire with a current.
- Is (2R,3S)-butane-2,3-diol chiral? - Chemistry Stack ExchangeThe staggered, conformation of (2R,3S)-butane-2,3-diol (1a) that you have shown does not have mirror planes but rather a center of symmetry, which is the reason that this conformation does not rotate plane polarized light.
- organic chemistry - What do (2S,3S) and similar notations mean ...When naming a organic compound, S/R-notation comes if there is a chiral atom present.The S/R-notation always accompanies a numerical such as (2S,3R)- where the numerical refers to the chiral carbon position in the molecule according to the IUPAC numbering while R and S representate the orientation of the chiral atom according to the Cahn–Ingold–Prelog priority rules.
