Octopus wiring is a common electric hazard found in households. A usual scenario is the permanent use of an extension cord to carry the total current drawn by multiple loads connected to it. Heat, end eventually fire, will most likely occur once the loads draw current that exceeds the ampere rating of the cord. Shown below are multiple loads connected in parallel across a 220-V AC source. The source provides a total current of IL to the loads through an extension cord with rating 20A. To prove that such setup is dangerous, determine the total current IL drawn by the loads. Only the magnitude of the current is needed. Express the answer in Amperes.
