A ___ is a device that forwards packets between networks by processing the routing information included in the packet.

An electric potential field is produced in air by point 1 μC and 4 μC located at (-2, 1, 5) and (1, 3, -1) respectively. The energy stored in the field is

Consider the following two statements and choose the correct answer.
Statement 1: The V-curves of a synchronous motor show relationship between armature current and supply voltage.
Statement 2: The plot of power factor against the field current of synchronous motor is known as inverted V curves.

The V-curves of a synchronous motor show relationship between Armature current (Ia) and Excitation current (If).
The Inverted V-curves of a synchronous motor show relationship between power factor (pf) and field excitation (If).

By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy stored in the capacitor is increased five times. The dielectric constant of the material is

Energy stored by capacitor, Q = ½CV²
Dielectric constant is directly proportional to C and capacitance is proportional to the dielectrical constant
