Define electric current. |
|
Answer» Flow of electrons The flow of electric charges across a cross-section of a conductor constitutes an electric current. It is defined as the rate of flow of the electric charge through any section of a conductor.Electric current charge/Timeor I = Q/tElectric current is a scalar quantity. An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. |

Define Electric charge. |
|
Answer» Electric Charge is defined as the amount of energy or electrons passing from one body to another either by conduction, induction or other specific methods. There are two types of electric charges namely positive charge and negative charges. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two-types of electric charges; positive and negative (commonly carried by protons and electrons respectively). |

What is ohm,s law |
|
Answer» V=IR Ohm’s law states that under no same temperature, electric current flowing through an ideal conductor is directly proportional to the potential difference across its ends.V ∝ IV = IR, R – Resistance ohms law gives a relationship between current and potential difference V=IR At constant temperature, the potential difference Is directly proportional to the current.. |

how is the leaf designed to absorb sunlight |
| Answer» Leaves have a large surface area to absorb more sunlight.Leaves are thin, hence carbon dioxide has only a short distace to diffuse into leaf cells.Leaves have large amounts of chlorophyll to absorb sunlight to transfer energy into chemicals.Stomata allows gaseous exchange to take place. Carbon dioxide enters and oxygen leaves the leaf through stomataThe internal structure of the leaf is also adapted to promote efficient photosynthesis:Cuticle: - Is non-cellular, thin, water proof and transparent. It allows light to pass through while protecting the leaf.Thin and transparent epidermis: - It allows more light to reach the palisade cells below.Palisade mesophyll: - has cells vertically arranged such that many can fit into a small space. The cells have large number of chloroplasts which helps to absorb more light.Spongy mesophyll: - Have large air spaces for fast diffusion of gases to and from the photosynthesizing cells.Veins (Vascular bundles): - They act as drain pipes distributing raw materials to the leaves and conducting away manufactured food to other parts of a plant. | |

Hor villi in small intestine increase surface area of absorption? |
|
Answer» Thanks yogita for your answerYou helped me a lot... The small intestines are packed with villi and microvilli that increase surface area of the small intestines, which helps with absorption.The small intestines are well adapted for absorbing nutrients during digestion by: being very long, having villi and microvilli that increase surface area, using muscular contractions to move and mix food, and receiving and housing digestive enzymes and bile that help the breakdown of food.

\u200dS.I unit of current... |
|
Answer» SI unit of electric current is ampere (A). Ampere is the flow of electric charges through a surface at the rate of one coulomb per second. This means if 1 coulomb of electric charge flows through a cross section for 1 second, it would be equal to 1 ampere. Yrr sabhi online kyo nhi aa rhe hai Ampere h saumya ji... Coulomb(C) |

While wire passes more electric current thin or thick? |
| Answer» The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. This is due to the fact that the resistance of a wire is inversly proportional to the square of its diameter. A thick wire has a greater diameter and hence lesser resistance making the current to flow through it more easily. On the other hand, a thin wire has smaller diameter and hence greater resistance to the flow of current through it. | |

Activity to explain about the factors on which the resistance of a conductor depends |
| Answer» Resistance of a conductor directly depends upon Length of the wire LInversely depends upon Area of Cross section of the conductor 1/ANature of material used.Therefore, R = ρ L/ALength of the conductor is double, means you are stretching that given length to double it. As a result, the wire becomes thin due to stretching. So its area of cross section will be halved(Since the volume remains constant). So new resistance RN = ρ 2L/A/2 = 4. ρ.L/A =4RHence the new resistance will become 4 times. | |
