Why Is It Possible For A Bird To Sit On A High Voltage Wire? Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird’s presence and continues to travel through the wire instead of through the bird’s body. A bird’s body is not a good conductor of electricity.
Why Silver Is Not Used For Making Electrical Wires? Though silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It’s very expensive compared to the widely used wiring material copper. Another reason for not using silver is that , it oxidizes easily

When Should Live Circuits Be Worked On? Per OSHA 1910.333(a)(1), live parts to which an employee may be exposed must be de-energized before the employee works on or near them, unless the employer can demonstrate that de-energizing introduces additional or increased hazards or is not feasible due to equipment design or operational limitations. Can you
Why Do Pliers Have Plastic Handles? The handles of tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber cover on them so that they do allow the current to pass through them and save the electrician from any electric shock. Why do the electrical testers have handles of
Why Is There A Gap Between Telephone Wires? Solution: (a) Most telephone wires are made out of copper, which contracts with drop in temperature and hence breaks in winter if it becomes too tight between the poles. (c) The gaps are left between the successive rails for making space for their expansion when there is
Which Tools Are Used For Wiring? Cable Tie Tools. Clamp Tools. Crimpers. Cutters & Strippers. Electrical Testers. Fuse Pullers. Heat Guns. Loom & Conduit Tools. What tools do I need for wiring? The Voltage Tester. The Digital Multimeter. The Non-Contact Voltage Tester. Lineman’s Pliers. A Quarter Inch Screwdriver. Multi Wire Stripper and Cutting Tool. What
Is Rubber Bad Conductor Of Electricity? Rubber itself usually cannot conduct electricity without any assistance. Rubber are poor conductors of electricity hence the reason you see electricians wear rubber gloves when they are working with electric wires. Which is not good conductor of electricity? Materials like glass and plastic are poor electrical conductors, and are
Can An Electrician Carry Out Electrical Repairs Outside During Heavy Rain? No, it is not safe for the electrician to carry out electrical repairs outdoors during heavy downpour. As rainwater consists of dissolved salts, it can conduct electricity. The electrician might get electric shocks and so he should not carry out any electrical repairs during
Why Do Copper Wires Have A Plastic Coating On Them? Most electrical wire is covered in a rubber or plastic coating called insulation. … The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through
