Hello,
If a positive charge is moved from point b to a, then we say a is positive to point b, and assign negative polarity to point b.
If a negative charge is moved from a to b, we still say the same.
Why? Please explain in simple terms if possible. Another question, if current and voltage polarity are in opposite directions of a circuit component it supplied power to the circuit, and if negative it takes power..why?
