Difference between Core Type and Shell Type Transformer The main difference between Core type and Shell Type Transformer is the constructional difference of their core and winding arrangement. In core type transformer, the magnetic core consists of two limbs and two yokes whereas in Shell type transformer, there are three limbs and two yokes. In core type transformer , the HV (High Voltage) and LV (Low Voltage) winding are wound on both the limbs. The winding are wound in such a manner to minimize the leakage flux. For this purpose, first LV winding is wound over which HV winding is wound. This also have advantage of lesser insulation requirement for having insulation between the LV winding and the core. Figure below shows a simple diagram of core type transformer. Shell Type Transformer: In Shell type transformer, the winding are interleaved or sandwiched on the central limb as shown in figure below. The LV winding is placed near the yoke and its size is made half of that of other win

Difference between Step-up and Step-down Transformer The main difference between step-up and step-down transformer is that, step-up transformer increases the voltage whereas a step-down transformer decreases the voltage. The secondary voltage of step-up transformer is more than that of its primary voltage whereas the secondary voltage of step-down transformer is less than its primary voltage. In fact, these two terms, i.e. step-up or step-down has significance from operational point of view. From construction and design point of view, there is no difference between step-up and step-down transformer. A given transformer can be used as step-up or step-down transformer. If the HV (High Voltage) winding is connected to supply main and LV (low voltage) winding to load, the transformer works as Step-down transformer. This is because, the transformer is delivering the power at a decreased voltage at secondary terminal. Figure below shows a step-down transformer. In the above figure, HV windin

Difference Between Charge & Current The most significant  difference  between the  charge  and the  current  is that the  charge  is the  physical property  of  matter , whereas the  current  is the  rate  of  flow  of  charges . Some other differences between charge and current are explained below in the tabular form. The electric charge is the physical property of matter which experiences the force when placed in an electric filed. It is of three types positive, negative and neutral. When these charges (generally electrons) move in the particular direction its generate current. And this current is used for illumination and mechanical works.

Difference Between Voltage &  Current The voltage and current are the two major aspects of electricity.The voltage is the type of the electromagnetic force whose effect causes the flow of electrical current in the circuit. The magnitude of a voltage and current depends on each other, but these two terms are different from each other in some ways. One of the major differences between voltage and current is that the voltage is the difference between the two points and the current is the flow of electrical charges between these two points of an electric field. Some others differences between them are explained below in the comparison chart.
