Num chuveiro ligado nas posições verão e inverno, com as seguintes características: 220V – 2200W/4400W. Calcule a corrente elétrica que circula na potência menor (verão) e maior (inverno), com a mesma tensão. Dica: isole a corrente elétrica na expressão P= i x U

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,

I = electric current for summer

For highest power,

I' = electric current for winters
