Question

. Find the current used and the resistance of the filament of a lamp rated at 240 V, 60W.

b. Give the colour coding of the connecting wires.​

Answer 1

Explanation:

Using the formula

$i = \frac{p}{v}$

here, given that

$p = 60w \: \: \: and \: \: \: \: v = 240v$

so,

$i = \frac{60}{240} = 0.25ampear$
