Thank you very much for this very helpful post If I insert equation in Word 2007 document, after I come out of the equation mode, the cursor seems to go somewhat in-between the space between the current line and the next, that is, the character's position gets lowered automatically. The size of...

Thanks to everyone for the informative replys

no two resistors are in series here there are two pairs of resistors, each pair contains two resistors in parallel, the two pairs are then in series Figure 1 and 2 are the same, only the subscripts for which resistors are parallel will change, otherwise the basic structure of the circuit in...

Why did you think that? 1A through 5Ohm = 5V across right most resistor Hence 5V across the middle 5 Ohm resistor, so current through middle one = 1A Similarly, 5V across 10Ohm resistor so current through it = 0.5Ohm Thus total current through leftmost 5Ohm resistor = 2.5A Voltage drop...

so we should say that work requires energy, but use of energy does not always imply work right?

Hi We all know that work done corresponds to energy used and calculated as force*distance So if we are pushing against a wall, it does not count as work done, as there is no motion However, aren't we still wasting energy when we are pushing against a wall? Since a certain amount of energy is...
