Sia ? 4 years, 10 months ago

Double fertilization occurs when one male nucleus fertilizes with an egg cell to form a zygote cell and the other male nucleus fuses with two polar nuclei to cause triple fusion. As these two types of fertilizations takes place at the same time in the ovule of the plant, it is known as double fertilization.

Kriti Singh 5 years, 2 months ago

Yes I am also confuse because by the formula R=rho L/A. Rho=RA/l Here,R and L are same So,Rho=A According to formula those wire which have more resistivity more thickness But,we know those wire which have low resistivity the flow of current through the wire is more,or more flow of current only through thick wire...... Yha by the formula or by the concept different answer aa rha h ..what is the right answer?

0Thank You

Khushi 5 years, 2 months ago

As both the lengths are same and also the resistance of the wire and resistivity of wire A is higher than the other, the thickness of wire A should be more because more resistivity, more the thickness.
