Odpowiedź:
1. D
2. Iloraz/czasu
3.
U = 9 V
I = 2 A
-----------------
R = ?
R = U/I = 9V/ 22A = 4,5 Ω
R = 4,5 Ω
R = 6 Ω
I = 0,75 A
---------------------------
U = ?
U = I*R = 0,75A * 6Ω = 4,5V
U = 4,5 V
R = 0,5 Ω
U = 1,5 V
---------------------------
I = ?
I = U/R = 1,5V/0,5A = 3 A
I = 3 A
4. C
A - amperomierz
V - woltomierz
