1.Yaka masa mіdі see for electricity, when 5kW * year of electricity is consumed? Elektroliz vіdbuvsya for springs 10 V, KKD installation-75% 2Value the weight of the balance, which can be seen for an hour by the electrolysis for 2 years, when a 2B voltage is applied to the range, and the range is set to 5 (Ohm). Visually spend electricity on the whole process VERY URGENT, WITH A DEPLOYED SOLUTION (GIVEN AND TD) ANSWER WITHOUT GIVEN AND TD = COMPLAINT I WILL DO IF WHAT IS THE BEST I beg ♡♡♡♡

Объяснение:
1. Вольтметр
2. 0,3 А
3. 4,8 В
4. U=R1*I=5*0,3=1,5 В лампа
5. U=R2*I=5*0,3=1,5 В реостат
6. Rобщ=R1+R2=5+5=10 Ом
7. I=U/R если U не меняется, то надо уменьшить сопротивление, тогда ток увеличится. Ползунок реостата подвинуть вправо .
8. N=UI=R1*I^2=5*0.3^2=0.45 Вт
9. Q=N*t=0.45*5*60=135 Дж лампа
10. Q=R2*I^2*t=5*0.3^2*5*60=Дж реостат
R2 =5 Ом - сопротивление равно половине полного сопротивления , потому что ползунок стоит на половине
I=0,3 А
11. Если брать сопротивление реостата 5 Ом, то
Rобщ=5*5/(5+5)=2,5 Ом при параллельном включении
