Question

A circuit has a fuse of 5 A. What is the maximum number of 100 W (220 V) bulbs that can be safely used in the circuit?

Please give correct answer.

Answer 1

Answer:

double can be safely used in circuit because 220 watt is used for home appliances only in small piece of home appliances you can use in a circuit it will be safe to use

Answer 2

Explanation:

Suppose x bulbs can be used safely.

Now, Power of 1 bulb = 100 W

So, Power of x bulbs, P = 100 × x watts

Potential difference, V = 220 volts

Current, I = 5 amperes

Power, P = V × I

100 × x = 220 × 5

x = 220 × 5 / 100

x = 11

Thus, the maximum number of 11 bulbs can be used.
