Step 1: Define electric current.
Electric current is defined as the flow of positive charge. By convention, current is considered to flow from the positive terminal to the negative terminal of a battery.
Step 2: Understand electron flow.
Electrons are negatively charged particles, and they actually flow from the negative terminal to the positive terminal of the battery.
Step 3: The current (flow of positive charge) is opposite to the flow of electrons (which is the flow of negative charge).
Step 4: Therefore, the direction of the current is opposite to the flow of electrons, and the correct answer is (2) opposite to the flow of electrons.
