Question

Q5.When a resistance of 460
Ohms is connected across 230
Volts supply,The current flowing
through the resistance
is..​

Answer 1

Answer:

pls mark as brainliest

Explanation:

Let us take an example of an incandescent bulb of 60 watts. And the power factor at unity means 1. As per Ohms law current is directly proportional to the voltage and inversely proportional to the resistance and power is the product of voltage and current and power factor. So current, I =W /V, so it will be 60 watts /220v =0.27 amperes approximately
