    in series all current is drawn by the resistance wire. whereas in parallel part of the current is drawn by the wire..

    in series there is an increase in length of the circuit while in parallel combination there is an increase in area since resistance is a quantuty which is directly prortional to length and inversely prortional to area the resistance decreae in parallel and increase in series

    Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity is useful in comparing various materials based upon their ability to conduct electrical currents. The unit of resistance is the ohm.
    Conductivity, by contrast, is the degree to which a conductor allows the flow of electricity through itself. The unit of conductivity is the siemens (S). It was formerly called the mho. Good conductors retain heat, minimizing the loss of energy from the electrical circuit. Copper wires, for example, are a material with excellent conductivity. Materials such as air, cloth, or rubber have very poor conductivity.

    Magnifying power is defined as the angle subtended at the eye by the image to the angle subtended (at the unaided eye) by the object.
    m = mo  × me = L/F0 × D/Fe
    To increase the magnifying power both the objective and eyepiece must have short focal lengths such as
    m = L/F0 × D/Fe

    In a step up transformer the number of turns in secondary coil is greater than number of turns in primary coil so the voltage induced get increased due to change in magnetic flux.
