A bulb is rated 60 W – 230 V. How much will be the current (in A) flowing through it, when connected to 115 V?
Question
Solution 1
To find the current flowing through the bulb, we first need to find the resistance of the bulb. We can use the power formula:
P = V^2 / R
Where: P = power (60W) V = voltage (230V)
Rearranging the formula to find R gives us:
R = V^2 / P
Substituting the given values:
R = 230^2 / 60 ≈ 881.67 ohm Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
