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

Answer:

I = 12.12 A

Explanation:

P = 2.5 kw = 2500 w

formula

$P=I^{2} R$

$I=\sqrt{\frac{p}{R} } =\sqrt{\frac{1500}{17} } =\sqrt{147.06} =12.12 amp$

Hope this helps
