Why conventional direction of electric current is oppisite to flow of charges?
Conventional electric current has been attributed a direction to account for a +ve value electric current flow from +ve to -ve voltage terminals. A potential or voltage difference causes electrons to move from the lower voltage end to higher voltage end. Now electrons being -vely charged, this flow of electrons constitutes a flow of negative chrage. the reverse direction of this flow hence constitutes a +ve flow. (This can be represented as flow of +ve charges called holes, absence of electrons) Hence conventional current is given a direction opposite of electrons, which flows from +ve to -ve end.
Why conventional direction of electric current is oppisite to flow of charges? You have to modify your question: Why conventional direction of electric current is oppisite to flow of NEGATIVE charges? By definition or by convention we have made a rule that the direction of flow of positive charges from one point to another point as the direction of current. When electrons which are negatively charged particles flow from one point to another point, it follows that they are opposite to the direction of flow if they were positively charged. Hence the direction of flow of negative charges is opposite to our conventional current. The current that is used for our electrical gadges are generally alternating current and not a d.c current. In that electrons move from transformer to house and then from the house to transformers say 50 times per sencond( frequency). The conventional current oscillates 50 times in each second and is always to the direction of electrons. Different countries use dif
