عندي 5 اسئله اريد حلها الصحيح او الطريقه
1- A copper wire of cross-sectional area 3*10^-6 m^2 caries a current of 10A . find the drift velocity of the electrons in this wire ? the density of copper is 8.95 gm/cm^2
2- Is the series equivalent resistor larger than either resistor or is it smaller
3- Is the parallel equivalent resistor larger than either resistor or is it smaller
4- What Is the series equivalent of three 53000 W resistors in series ?
5- What is the equivalent of three 670 W resistors in parallel? You may want to do this problem in two steps ?
