To determine the voltage drop across a worker due to a body current of 50 mA, we can use Ohm's Law, which states that Voltage (V) = Current (I) × Resistance (R). The typical body resistance for an adult is approximately 1,000 ohms, although this can vary based on various factors such as skin condition and moisture.

In this scenario, you have a current of 50 mA, which is equivalent to 0.050 A. By applying Ohm's Law:

Voltage = Current × Resistance

Voltage = 0.050 A × 1,000 ohms

Voltage = 50 volts

This calculation clearly shows that a body current of 50 mA results from a voltage drop of 50 volts across the worker. This is the basis for determining the correct voltage drop corresponding to the given current and typical resistance.
