Why are bulb not placed in Resistors? |
|
Answer» \xa0A bulb is a non-ohmic resistor. This means that, the resistance of the bulb changes with temperature.For Ohm\'s law to be obeyed V/I = R. Thus, resistance needs to be constant even when I and V change.Now, if we replace the resistor with a bulb, when current changes, temperature of the filament of bulb also changes. This changes the resistance of the bulb.Thus, bulbs cannot be used to prove Ohm\'s law. Bulb is considered as v not r |

Write a test to identify the presence of ethanoic acid? |
|
Answer» Bromine water test In order to identify presence of carboxylic acids, they should treat with bases like Sodium hydroxide (NaOH).Formation of salt (sodium acetate) and water confirms the presence of acids. CH₃COOH + NaOH → CH₃COONa + H₂O Not only with bases but carbonates and bicarbonates also forms sodium acetate. Reaction of ethanoic acid with ethyl alcohol produces ethyl acetate. Formation of ethyl acetate (ester) indicates sweet smell. CH₃COOH + C₂H₅OH →CH₃COOC₂H₅ + H₂O ......☺ |

Resistance?? |
|
Answer» Resistance is the opposition that a substance offers to the flow of electric current. It is represented by the letter R. Its unit is ohm. do you want the defination of resistance?? Resistance is a property of conductor due to which it resists the flow of electric current through it. ... Variable Resistance: The component of an electric circuit which is used to regulate the current; without changing the voltage from the source; is called variable resistance. Obstruction for a current to flow is called resistance. |

Disadvantages of grafting in 5 point |
|
Answer» disadvantages:-1.grafting is very complex process of vegetative propagation .one has the skill and knowledge about like how to successfully graft a plant.2.In order to graft a scion over a stock we have to find a scion which will fit into the stock or at least in the shape in which they fit together .so to do so we have to do a great work.3.there is not 100% success if we do this process of reproduction. Like if we do this type of vegetative propagation .it is possible that one plant scion cant compatible with another plant stock.4.grafting can only be done when plant is dormant like in late winter to early spring. And usually we graft in same genus .so that is not sure we can do grafting in any plant. Disadvantages of grafting\tIt require specialised skills to perform grafting.\tThe life span of grafted plants is short as compared to seed propagated plants.\tSuccessful grafting is often limited to plants that are related because they must share similar characteristics, such as color, fruit and growth habit.\tIt can lead to the spread of alien plant species, resulting in the alien species growing out of control and becoming a pest. |
