The hot resistance of a 240 V filament lamp is 960Ω. Find the current taken by the lamp and its power rating
Question
Solution 1
Step 1: Find the Current
We can use Ohm's Law to find the current. Ohm's Law states that the current (I) is equal to the voltage (V) divided by the resistance (R).
So, I = V/R
Given that V = 240V and R = 960Ω, we can substitute these values into the equation:
I = 240V / 960Ω = 0.25A
