Question

If length of tungsten filament is 4 m cross section is 12.8 resistence of filament is​

Answer 1

Answer:

Use power and voltage to determine resistance.

Use power and voltage to determine resistance.R = V2 ⇐ P = V2

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R P

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.R = V2

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.R = V2P

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.R = V2PR = (120 V)2

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.R = V2PR = (120 V)260 W

Use power and voltage to determine resistance.R = V2 ⇐ P = V2R PNumbers in. Answer out.R = V2PR = (120 V)260 WR = 240 Ω.....
