What energy transformation takes place in a dry cell B electric fan?
1) in dry cell – chemical energy is converted to electrical energy. 2) In electric fan – electrical energy is converted to mechanical energy and wind energy .
Which energy is converted in an electric cell?
An electrical cell is an “electrical power supply”. It converts stored chemical energy into electrical potential energy, allowing positive charges to flow from the positive terminal to the negative one through an external circuit.
How many terminals does an electric cell has name them?
two terminals
Which metal is generally used to make electric wires?
Copper is regarded as the standard in electrical conductors, second only to silver in conductivity, but far more plentiful and therefore economical.
Why we should never touch live electric wires or electric cables that have fallen on roads?
1 Answer. (a) It is more dangerous to touch the live wire rather than the neutral wire because live wire has a high potential of 220V, where as neutral wire has zero potential. (b) Bird’s body is not connected to the earth, so no current flows through its body into the earth.
Why it is dangerous to touch electric wires?
If you touch it, you may complete a circuit between the live wire and the earth (because you’ll be standing on the floor), so you get a shock. The flow of charge (current) in a circuit can travel in one direction around the circuit only.
How do you protect yourself from electrical hazard?
Preventative steps
- Inspect wiring of equipment before each use.
- Use safe work practices every time electrical equipment is used.
- Know the location and how to operate shut-off switches and/or circuit breaker panels.
- Limit the use of extension cords.
- Multi-plug adapters must have circuit breakers or fuses.
