Question

R1=4 Ом R2=6 Ом R3=10 Ом U2=1,8 В I-? Uобщ.-?

Answer 1

I = U2 / R2 = 1.8/6 = 0.3 А

Uобщее = Rобщ * I = (4+6+10)*0.3 = 6 Ом

Answer 2

To find the current (I) and the total voltage (Uобщ. - the voltage across the entire circuit), we need more information about the circuit's configuration. Specifically, we need to know how the resistors (R1, R2, and R3) are connected, whether they are in series or parallel.

Assuming the resistors are connected in series: In a series circuit, the current passing through each resistor remains the same, and the total resistance (R_total) is the sum of individual resistances.

R_total = R1 + R2 + R3 = 4 Ω + 6 Ω + 10 Ω = 20 Ω

Next, let's calculate the current (I) using Ohm's law: Ohm's law: U = I * R

We know that U2 = 1.8 V (voltage across R2) and R2 = 6 Ω.

1.8 V = I * 6 Ω

Now, solve for I: I = 1.8 V / 6 Ω I = 0.3 A

So, the current (I) flowing through the entire circuit is 0.3 Amperes.

To find the total voltage (Uобщ.), we can use the total resistance (R_total) and the current (I):

Uобщ. = I * R_total Uобщ. = 0.3 A * 20 Ω Uобщ. = 6 V

Therefore, the total voltage (Uобщ.) across the entire circuit is 6 Volts.
