[QUOTE="IronaSona, post: 509259, member: 33765"] Hello , i got a give a questions Q When a direct current of 2A is passed through a coil, the potential difference across the coil is 20V. When an alternating current of 2A at a frequency of 40Hz is passed through the coil, the potential difference across the coil is 140V. a) Find the current in the coil if it is connected to a supply of 230V, 50Hz. b) What is the phase shift of the current in the coil with respect to the supply voltage? I been looking all over the google/youtube how to do that but every single time i get given different formulas/equations/answers , and am not quiet sure what in need to do. [/QUOTE]
