What is potential? |
| Answer» Electric potential is defined as work done on per unit charge.S.I. unit of electric potential is Volt.The electric potential is said to be 1 volt if 1 joule work is done in moving 1 coulomb charge.Electric potential is a scalar quantity.Voltmeter is used to measure electric potential difference. The electric potential difference is the cause of electric current. | |

Diffen ohms law |
| Answer» Ohm’s Law states that the potential difference between two points is directly proportional to the electric current.This means; potential difference V varies as electric current.Or, V α I⇒ V/I = R⇒ V = IRWhere R is constant for the given conductor at a given temperature and called resistance. Resistance is the property of conductor which resists the flow of electric current through it. | |

What is dual nature of the light |
| Answer» Dual nature of Electro-magnetic radiation suggests that the electro-magnetic radiations are both particle and wave in nature. This theory helps us to predict many properties of the atoms on the basis of their structures. This can be explained on the basis of refraction, diffraction, interference of light ( showing wave nature ) and photoelectric effect and black body radiation ( showing particle nature of light ).For example, wave nature of electro-magnetic radiations can help us in understanding the wavelength, frequency of the radiations emitted by atoms and the particle nature of electro-magnetic radiations can explain black-body radiation, photoelectric effect, variation of heat capacity of solids and line spectra of atoms and all these are characteristic of a particular atom and depend on the structure of the atom. | |

Why do we rub the magenesium ribbon before burning? |
|
Answer» Its because in contact with the atmosphere,magnesium present in the outer layer of the magnesium ribbon reacts with the atmospheric oxygen thus forming MgO.By rubbing it with a cloth,we remove the outer layer of MgO and thus there is only Mg now to be burned and that\'s what is needed for the experiment. Because it has protective layer of basic megnesium carbonate so we rubb the magnesium ribbon |

State heating effect of the current ? |
| Answer» When electric current is supplied to a purely resistive conductor, the energy of electric current is dissipated entirely in the form of heat and as a result, resistor gets heated. The heating of resistor because of dissipation of electrical energy is commonly known as Heating Effect of Electric Current. Examples: When electric energy is supplied to an electric bulb, the filament gets heated because of which it gives light. The heating of electric bulb happens because of heating effect of electric current. | |

How do guard cells control the opening and closing of stomach |
| Answer» Stomata are the tiny pores present on the surface of the leaves, by the process called the large amount of gaseous exchange takes place in leaves through these pores. But exchange of gases also takes place on the surface of stem roots and leaves. A large amount of water is lost through these pores. The plant closes these pores when carbon dioxide is not required for photosynthesis.Guard cells performs the opening and closing of these pores. The guard cells swell when water flows into these pores and stomatal pores get open, and as the water shrinks the guard cell closes. | |

Define electric power and electric charge ? |
| Answer» Electric power : SI unit of electric power is watt (W).1W = 1 volt x 1 ampere = 1V x 1A1 kilo watt or 1kW = 1000 WConsumption of electricity (electric energy) is generally measured in kilo watt.Unit of electric energy is kilo watt hour (kWh)1 kWh = 1000 watt X 1 hour = 1000 W x 3600 sOr, 1kWh = 3.6 x 106 watt second = 3.6 x 106 JElectric charge : If a net electric charge (Q) flows through a cross section of conductor in time t, then; I = Q/tSI unit of electric charge is coulomb (C).One coulomb is nearly equal to 6 x 1018 electrons. | |
| 61013. |

What do you mean by electric current |
|
Answer» The rate of flow of electricity in per unit time is called as electric current An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). ... Electric current is measured using a device called an ammeter. |
