Question

Calculate the resistance of iron filament if it operate on 230V supply and draw a current equal yo 2A

Answer 1

Answer:

Making an assumption that the set up works in a DC format , we can apply ohm's law V = IR

V = Voltage of the source

I = current drawn

R = Resistance offered by the conductor

thus R = V/I

R = 230V/2A = 115ohms.

hope this helps.
