Question

The heating element has a power of 2.5kW. The resistance of the heating is 17(ohms)

Calculate the current in the heating element. Give answer to 2s.f
Write any equations that you use.

Answer 1

I = 12.12 A

Step-by-step explanation:

P = 2.5 kw = 2500 w

formula

`P=I^(2) R`

`I=\sqrt{(p)/(R) } =\sqrt{(1500)/(17) } =√(147.06) =12.12 amp`

Hope this helps
