Question
What is the largest number of 1000W bulbs that can be connected to a 240V supply with a 5A fuse?
Solution
To find out the maximum number of 1000W bulbs that can be connected to a 240V supply with a 5A fuse, we need to follow these steps:
-
First, we need to find out the total power that the supply can provide. This can be calculated using the formula P=IV, where P is power, I is current, and V is voltage. Substituting the given values, we get P = 240V * 5A = 1200W.
-
Next, we need to find out the power consumed by each bulb. We are given that each bulb consumes 1000W.
-
Finally, we divide the total power that the supply can provide by the power consumed by each bulb to find out the maximum number of bulbs that can be connected. So, 1200W / 1000W = 1.2.
Since we can't have a fraction of a bulb, we round down to the nearest whole number. So, the maximum number of 1000W bulbs that can be connected to a 240V supply with a 5A fuse is 1.
