A fault in a household appliance caused a person to receive an electric shock before an electrical safety device tripped. The mean power transferred to the person during the shock was 1.8 W1.8\text{ W}1.8 W. The potential difference across the person was 120 V120\text{ V}120 V. Calculate the electrical resistance of the person.
