Dear Friends, i had an exam today where i had to mark the answers on OMR answer sheets.
But unfortunately in some answers i marked a bit out of the circle, will it lead to rejection
Am sorry, if this topic does not belong to this section, as i am new, kindly oblige
Can root RMS value of current (what we study in Alternating currents) be negative?
i feel that it can surely be negative as it is a root, but my teacher told that it can't be negative and showed just one...
