1. **Problem statement:** Find the resistance of a device when a current of 2 amperes flows through it at a voltage of 230 volts. 2. **Formula used:** Ohm's Law states that resistance $R$ is given by the formula: $$ R = \frac{V}{I} $$ where $V$ is voltage and $I$ is current. 3. **Given values:** - Voltage, $V = 230$ - Current, $I = 2$ 4. **Calculation:** Substitute the given values into the formula: $$ R = \frac{230}{2} $$ 5. **Simplify:** $$ R = 115 $$ 6. **Answer:** The resistance of the device is $115$ ohms.
