An electric oven consumes 1 kW electric power when operated at 220 v write the capacity of the fuse suitable for ur device .give reason for ur answer
Answers
Answer:
5 A
Step by step explanation:
It is given that:
- P = 1 KW
- V = 220 V
It is required to know the capacity of the fuse; which is the current.
P = I*V
1000 = I*220
Therefore, the current flowing in the device; I = 1000/220 = 4.54 A
Therefore, the fuse must be higher than 4.54 A because the function of the fuse is to protect a system from short circuit current or high currents.
Therefore, I would suggest the fuse capacity to be 5 A.
In the given question, the voltage required is mentioned as 220 volts.
The power to be used is mentioned as 1000 watt.
To solve the problem, the formula power+ voltage x current is to be used.
According to this formula, therefore, current = Power/ voltage.
Therefore current produced = 100/220 = 4.54 amperes.
Hence the correct answer of the given question is 4.54A
