    Sia ? 4 years, 4 months ago

    Ohm's Law tells us that if a conductor is at a constant temperature, the current flowing through the conductor is directly proportional to the voltage across it. This means that if we plot voltage on the x-axis of a graph and current on the y-axis of the graph, we will get a straight-line.

    Ohm’s law states the relationship between the current flowing through a metallic wire and the voltage across its terminals.

    The law states that the current flowing through a conductor is directly proportional to the voltage across it.

    Mathematically, the law is represented as follows:

    V = IR

    where R is the constant for a given metallic wire known as resistance.

    Sher Singh 4 years, 4 months ago

    Ohm law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends when physical conditions like pressure temperature be kept constant. V = IR Where r is a resistance of that conductor. The graph between current and potential difference is always straight line.

    When an electrical charge is moving or an electric current passes through a wire, a circular magnetic field is created. This can be seen with iron shavings or filings on a card that will align in the magnetic field when a current is passed through a nearby wire.

    (i) for minimum, connect the capacitors in series.

    Thus, 1/Ceq = 1/8 + 1/12 + 1/24

    thus, Ceq = 4 μF

    then formula for finding charge = Ceq*V

    therefore, charge = 4*100 = 400μC

    (ii)  for maximum capacitance,

    connect the capacitors in parallel

    thus, Ceq = 8 + 12 + 24 = 44μF

    thus, charge = 100*44 = 4400μC

    2Thank You

    Sher Singh 4 years, 4 months ago

    Capacitors can be connected in two different ways : for getting maximum capacitance they are connected in parallel combination and to get minimum capacitance they are connected in series combination. So capictance in parallel is:44uC and capacitance in series is:4uC

    Also (1) E is either attractive or repulsive in nature but G is always attractive (2) gravitational force is weaker then electrostatic force (3) also ; if insulator (dielectric ) is placed between the two charge then it's electrostatic force decreases whereas in gravitational force there is no effect of it ।

    Sher Singh 4 years, 4 months ago

    Electrostatic force is a force in between two charged particles whereas gravitational force is a force between two masses. Electrostatic force, F=kqQ/r^2 and Gravitational force, F=GmM/r^2 Where k is electrostatic constant and g is gravitational constant.

    If both assertion and reason are true but the reason is not the correct explanation of assertion.
    Electric lines of force never cross each other. Electric field at a point add up vectorally to give one resultant electric field. So, they do not have independent existence at the point of superposition so, electric lines of force do not cross each other(crossing of electric lines of force at a point means at a point two fields are having independent existence).

    The mutual repulsion of excess positive charges on a spherical conductor distributes them uniformly on its surface. The resulting electric field is perpendicular to the surface and zero inside. Outside the conductor, the field is identical to that of a point charge at the center equal to the excess charge.
