VBQ-
Teacher has explained students of grade 8,the risks of manhandling electric cells.
1) why should the electric cells be handled properly?
2) what precautions are to be taken to prevents mishaps?
3) what values do you learn?
Answers
Injuries caused by electricity include electrical shock, burns, and falls due to electrical shocks and burns. Electrocution is a fatal electrical shock. Electrical shock occurs when current passes through the body. The severity of the shock depends on:
Amount of current flowing through the body,
Path of current through the body,
Length of time the body is in the circuit.
Fire Hazards
Too much current flowing through a wire can cause a power cord to overheat and start a fire. Sparks from electrical equipment can ignite flammable materials.
GENERAL RULES FOR ELECTRICAL SAFETY
Use electrical cords only if they are in good condition. Cords must not be cracked, frayed, or have corroded prongs.
Do not use 3-to-2 prong adapters unless other grounding provisions have been made. Plug 3-prong plugs into 3-prong outlets.
Use power strips that have circuit breakers or fuses. Do not link power strips in series.
Answer:
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. The electrochemical cells which generate an electric current are called voltaic cells or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells.[better source needed] A common example of a galvanic cell is a standard 1.5 volt[better source needed] cell meant for consumer use. A battery consists of one or more cells, connected in parallel, series or series-and-parallel pattern.
