Question

What should be the rating Of fuse wire when an electrical heater of 2KW is the connected to 200V supply

Answer 1

Answer:

10 amperes

Explanation:

Given :

• Power in the electric heater = 2 Kw

• Voltage (or) potential difference = 200 volts

To find :

• Rating of the fuse wire

1 Kw = 1000 watts

2 Kw = 2000 watts

Rating of the wire to be good is generally given as : Power / potential difference

Rating = 2000/200

Rating = 10 Amperes

A wire with a rating of 10 amperes should be used for safety purposes and a higher voltage could cause short circuit

Answer 2

Explanation :

We have power of heater is 2KW . Potential difference is 200V

What is rating of fuse wire?

___________________________

Here,

□ Power of heater = 2KW

= 2 × 1000

= 2000 W

□ Potential difference = 200V

Rating of fuse wire is given by,

Rating = Power/Potential difference

Substituting values,

⇒ Rating = 2000/200

⇒ Rating = 10

⇒ Rating = 10 A

∴ Rating of fuse wire is 10 Ampere.
