A reviewer is passed through by an electric current of 15 mA when a potential difference of 120v is applied to stop the resistance

To calculate the resistance in this scenario, you can use Ohm's law, which states that resistance (R) is equal to the voltage (V) divided by the current (I): R = V / I In your case, the potential difference (V) is 120 volts, and the current (I) is 15 milliamperes, which is equivalent to 0.015 amperes. Now, plug these values into the formula: R = 120 V / 0.015 A R = 8000 ohms So, the resistance is 8000 ohms (or 8 kilohms).
