Question

1) Calcule a corrente elétrica nos circuitos a seguir:

a) E=12 V  R=220Q
B) E=96 V R=32Q
c)E= 180 V R=46Q

Answer 1

$a) U = |R*I\\ 12 = 220*I\\\\ I = \frac{12}{220} \\ \\I = 0,05 A\\\\b) U = |R*I\\\\96 = 32*I\\\\I = \frac{96}{32}\\\\I = 3A\\\\ c) U = |R*I\\\\180 = 46*I \\\\I = \frac{180}{46} \\\\I = 3,91A$
