Homework Statement
V = IR is used to define resistance. why can't it be used to define p.d.?
The Attempt at a Solution
i suggested that sometimes the current can be zero, but there is a p.d. so the equation does not hold.
but my teacher says that the answer is more towards the concept of variables, independent and dependent. i can't understand how?
thanks
