Diviseur de tension

Calculez U_R1 et U_R2

U_ard= 5V, R1 = 1\(k\Omega\), R2 = 1\(k\Omega\)

U_R1 = 2,5\(V\), U_R2 = 2,5\(V\)

U_R1 = U_ard * R1 / (R1 + R2) = 5 * 1000 / (1000 + 1000) = 2,5 \(V\)

U_R2 = U_ard * R2 / (R1 + R2) = 5 * 1000 / (1000 + 1000) = 2,5 \(V\)

Calculez U_R1 et U_R2

U_ard= 5\(V\), R1 = 3\(k\Omega\), R2 = 1\(k\Omega\)

U_R1 = 3,75\(V\), U_R2 = 1,25\(V\)

U_R1 = U_ard * R1 / (R1 + R2) = 5 * 3000 / (3000 + 1000) = 3,75 \(V\)

U_R2 = U_ard * R2 / (R1 + R2) = 5 * 1000 / (3000 + 1000) = 1,25 \(V\)
