To find the current when you know voltage and total resistance, you

Explanation:
Current is how much charge flows per second, and it’s set by how much voltage is pushing through and how much resistance resists that push. Ohm’s law ties these together: V = I R. If you know the voltage and the total resistance, you solve for current by rearranging to I = V / R. So you divide the voltage by the resistance to get the current. For example, 12 volts across 6 ohms gives 2 amperes. Multiplying voltage by resistance would not give current (it would mix units incorrectly), and adding or subtracting voltage and resistance isn’t a valid operation to find current.
