Question

R1=10(ом ).R2=15(ом).R3=20(ом).E=24В.r0=2(ом).Uab=?

Answer 1

To calculate the voltage (Uab) across points A and B in the circuit, you can use the formula for voltage division:

Uab = E * (R2 / (R1 + R2 + R3))

where:

• E is the source voltage (24V in this case).
• R1, R2, and R3 are the resistances in ohms (10Ω, 15Ω, and 20Ω, respectively).

Now, let's plug in the values:

Uab = 24V * (15Ω / (10Ω + 15Ω + 20Ω)) Uab = 24V * (15Ω / 45Ω) Uab = 24V * (1/3) Uab = 8V

Therefore, the voltage across points A and B (Uab) is 8 volts.
