Ohm's Law

Given:

   Current (I) = 60.0 A

    Voltage (V) = 12 V

Required: Resistance (R)

Formula:

     R =

Solution: V = IR

                R =

                R =

                R = 0.2 ohms

Answer: Resistance = 0.2 ohms, the resistance of the electric motor

Explanation:

An eletric circuitOhm's law shows the relationship of the current, voltage, and resistance. The current refers to the flow of electrons in an electric circuit. It is driven by the difference in potential energy between two points, known as voltage. As the current flows, there is an opposing force known as resistance. The unit for current is in amperes, the unit for voltage is in volts, the unit for resistance is in ohms. According to Ohm's law, the current is directly proportional to voltage and inversely proportional to the resistance. Ohm’s law holds true if the provided temperature and the other physical factors remain constant. It means the greater the voltage, the greater the current, and vice versa. Also, the greater the resistance, the lesser the current or flow of electrons, and vice versa. Ohm's law can be represented by the formula, V=IR. The formula for other quantities can be derived from the formula, specifically, I = and R = .
