Final answer:
Electric clippers and hair dryers utilize electricity to function. They use alternating current from wall sockets and include mechanisms to generate heat and blow air. Precautions must be taken to avoid using these devices near water to prevent electric shocks.
Step-by-step explanation:
Electric clippers and hair dryers are examples of barbering tools that use electricity. These devices are plugged into a wall socket, connecting them to the power grid that provides an alternating potential (AC potential). This potential pushes charges back and forth in the circuit of the device, creating an alternating current which powers the device. Hair dryers also use the electricity to generate heat, which is then blown out by a fan, using air to dry the hair quickly.
When considering safety precautions, it is important to not use such electrical devices near water to prevent the risk of electric shocks. The combination of electricity and water can be very dangerous because water can conduct electricity, potentially leading to electrocution. This is why it is advised to keep electrical devices away from water and to have dry hands when operating them. Also, one should never throw water on an electric fire as it can cause the fire to spread or increase the risk of electric shock.
