How to kill filamentous phages?

How to preserve filamentous fungi in distilled water ?

At what temperature does the filament of electric bulb glows ?

Why does the filament of an electric lamp glow, when current passes through it ?

Apple,

On the same voltage, the resistance of the filament of the bulbs of 200 watt and 100 watt are R1 and R2, then (1) The value of R1 is twice that of R2 (2) The value of R2 is four times the value of R1 (3) The value of R1 is four times that of R2 (4) The value of R2 is twice that of R1

An electric bulb has a filament made of (a) Copper (b) Iron (c) Lead (d) Tungsten

The filament of an electric lamp becomes white hot but the lead in wires holding the filament are only slightly heated because they (A) Have smaller current passing through them (B) Have very low resistance (C) Have higher melting point (D) Are made of black iron

Two lamps have tungsten filaments. The resistances of two lamps at incandescence are r and R, R being greater than r. These lamps are connected in series. Then (1) The lamp with resistance r will shine more brightly (2) The lamp with resistance R will shine more brightly (3) Both will shine equally brightly (4) No prediction can be made regarding brightness

The most largely used metallic filament in a 60 watt bulb is (1) Aluminium (2) Titanium (3) Tungsten (4) Nickel

Explain the filamentous structure of Rhizopus?

The filament of an electric bulb is made of 1 Iron 2 Nichrome 3 tungsten 4 Graphite

Germanium, Google, Graphite India, Tungsten,

state the disadvantages of carbon filament???
