In case of filament lamp at higher voltages, the resistance of lamp

A component that allows unidirectional current to pass through it is

Visible light has wavelength of

Component which obeys ohm's law is called

Two waves with phase difference 180° have resultant of amplitude

If current and potential difference are directly related then object follows

Resistivity is measured in

From double-slit experiment, the quantities to be measured are

In semiconductors upon increasing temperature, conductivity

A filament lamp is

Resistance of a particular wire depends upon

If two waves are in phase and have same amplitude then resultant wave has

Current and voltage are

Resistivity of lead is {{}}

Resistance of metal is affected by

Constructive interference happens when two waves are

At constant temperature, resistance and cross-sectional area are

At threshold voltage, resistance of diode

Effect of diffraction is greatest if waves pass through a gap with width equal to

A rectifier converts
