Explanation:

Let us assume that the question says,"In a shower connected in summer and winter positions, with the following characteristics: 220V - 2200W / 4400W. Calculate the electric current that circulates at the lowest (summer) and highest (winter) power, with the same voltage. Tip: isolate the electric current in the expression P = Ix V "

It is given that,

In a shower connected in summer and winter positions, with the following characteristics: 220 V - 2200 W / 4400 W.

It means lowest power is 2200 W and highest power is 4400 W

For lowest power,

[tex]P=VI[/tex]

I = electric current for summer

[tex]I=\dfrac{P}{V}\\\\I=\dfrac{2200}{220}\\\\I=10\ A[/tex]

For highest power,

[tex]P'=VI'[/tex]

I' = electric current for winters

[tex]I'=\dfrac{P}{V}\\\\I'=\dfrac{4400}{220}\\\\I'=20\ A[/tex]
