Question

if three identical lamps are connected in parallel and the combined resistance 150 ohm; find the resistance of one lamp. Ans. 450 ohms

Answer 1

`\huge\boxed{\sf R = 50\ ohms}`

Step-by-step explanation:

Given Data:

Equivalent Resistance =
`R_T` = 150 Ohm

Required:

Resistance of one lamp = R = ?

Formula:

`R_T` = R + R + R

Solution:

150 = 3R

Divide 3 to both sides

50 ohms = R

R = 50 ohms

`\rule[225]{225}{2}`
