This lesson is intended as a revision of basic direct-current (DC) circuits . It was discovered in the 19th century that certain materials (so-called ideal resistors) have a current through them I that is proportional to the potential difference (voltage) across them V. This is not a fundamental law of physics (like momentum conservation) but is an observed behavior which some materials roughly follow (like the friction law we covered earlier in the course). ... This equation is called Ohm's law. ...

... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...
