8. What current flows through a 1.15 kW electric fire at a potential difference of 230 V? (Remember that 1.15 kW is 1,150 W)
9. Would it be best to use a 3A, 5A or a 13A fuse for the fire above? Explain
why.

I = 5[amp]

Explanation:

Electrical power is defined as the product of voltage by current.

where:

P = power = 1150 [W]

V = voltage = 230 [V]

I = current [amp]

Now replacing:

A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]

i had this question and the answer was 3.15 miles.
