Is the acceleration due to gravity different in south pole and north pole

Mohak Tandon Asks – “ “Is the acceleration due to gravity different in south pole and north pole?” Answer: As per theory, acceleration due to gravity changes with altitude, depth and latitude. If we consider that the variation of g with latitude is caused by rotation of earth only, then the value of g will be same for both [...]

Potential Difference – misconception

What actually it means when we say “potential difference across..” ? Does it indicate that the somehow the energy level of electrons across it is less than on the other side or is it just the amount of energy consumption across it. If latter is true then in AC we’ve voltages which dont algebraically add [...]
