In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
Electricity is the essential need for everyday life.
Electricity problems are caused due to failures and errors in the electricity network, these might include man power error at the source, circuit failure, wires burn out etc. apart from these certain natural calamities also can harm the power supply, which include storms which harm the wires transmitting the electricity, heavy rain which causes damage to the electricity poles .
Solar flares and grid failures also lead to electricity failures.
