Multispectral Remote Sensing.  Multispectral remote sensing is defined as the collection of reflected, emitted, or backscattered energy from an object or area of interest in. multiple bands of electromagnetic spectrum; while Hyperspectral remote. sensing involves data collection in hundreds of bands.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.Resistors can also be used to provide a specific voltage for an active device such as a transistor.All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it.esistors can also be used to provide a specific voltage for an active device such as a transistor.

A varistor or metal oxide varistor (MOV) is a special resistor that is used to protect circuits against high transient (short term) voltage. These surges and spikes attacks the equipment by the power line and will destroy the power supply of the equipment.
