Question
Which of the following is a reason for excessive
current in electrical circuits? I. Direct touching of wires II. Connection of many devices to a single socketSolution
One reason for excessive currents in electrical circuits is the direct touching of wires . This may happen if the insulation on the wires has come off due to wear and tear. Too many appliances on a single socket implies too much load is shared across several nodes. The current will rise much higher as a result of this.
