Suppose there are m numbers of conductors arranged in parallel. We can mark the conductors as 1, 2, 3, …, m. Current I₁, I₂, I₃, …, Iₘ flow through the conductors respectively. Also, in a system, we can consider the sum of these currents to be zero. So, we can write,I1+I2+I3+⋯+Im=0I_1+I_2+I_3+\cdots+I_m=0We need to calculate the … Read more

Let A be the cross-section of a conductor. The current I is flowing in the inward direction with respect to the reference plane. Suppose there is another conductor at a distance D. Here, current I is flowing outward with respect to the reference plane. Now, at conductor A, the magnetic field intensity at any point … Read more

Suppose there is a current-carrying conductor. This conductor carries a current of I amperes. Now, we shall consider a small length dx of the conductor. Also, we shall consider a point P as the observation point. The position vector of that point from the conductor segment dx is r. This means the straight distance between … Read more

The storage of fossil fuel like coal is going to be finished in near future. So, we need an alternative source of energy for large scale electric energy generation. This is where nuclear energy comes into picture. Many developed and developing countries have found the tremendous capability of electricity generation of nuclear power. Theory of … Read more

Hydroelectric power is the oldest and cheapest method of large-scale electricity generation. Remarkably, it runs entirely on water. Furthermore, it produces zero direct emissions. Best of all, it costs almost nothing to operate once built. In addition to power generation, most hydro projects also control floods, store irrigation water, and support navigation — all simultaneously. … Read more
