Read the passage given below and answer the following questions: In spite of the predictions of stable noble gas compounds since at least 1902, unsuccessful attempts at their synthesis gave rise to the widely held opinion that noble gases are not only noble but also inert. It was not until 1962 that this dogma was shattered when Bartlett in Canada published the first stable noble gas compound XePtF_(6) . This discovery triggered a worldwide frenzy in this area, and within a short time span many new xenon, radon, and krypton compounds were prepared and characterized. The recent discoveries show the ability of xenon to act as a ligand . The discovery by Seppelt’s group that more than one xenon atom can attach itself to a metal center which in the case of gold leads to surprisingly stable Au- Xe bonds. The bonding in [AuXe_(4)]^(2+) involves 4 Xe ligands attached by relatively strong bonds to a single Au(II) center in a square planar arrangement with a Xe-Au bond length of about 274 pm This discovery provides not only the first example of multiple xenon ligands but also represents the first strong metal - xenon bond. (Source: Christe, K. O. (2001). A renaissance in noble gas chemistry. Angewandte Chemie International Edition, 40(8), 1419-1421.) In the complex ion [AuXe_(4)]^(2+) , Xe acts as :

i. Tara, after completing her exams, went to her grandmother's house along with her younger brother Rahul. One day, Rahul came home after playing and switched on the fan as well as air conditioner. At the same time, his grandmother was preparing a milkshake of him using a mixer. Suddenly, there was a big sound and the electricity of the house got shut down. Tara then called an electrician. He said the main reason of supply to shut down was overlading Both Tara and Rahul asked few questions to the electrician as given below. What answers would the electrician has given below. What answers would the electrician had given to these questions? Is overloading and short circuiting same? When does short circuiting take place?
