4.0.1 2.OA {2.0.2 a) what is the voltage arcoss 4-2? b) what is the total current labeled "I" in the diagram?

V1 1] Consider the circuit in the diagram with an unknown resistor R. The known resistor is R₁ = 1k, the power supply voltage is V, 12 Volts, and the measured output voltage is Vx8 Volts. Multisim insists on values, so I put -10 for the 12V unknown. I'll try to take this approach consistently in the homework diagrams, if possible. A) Determine the value of R. B) Determine the current i through the resistors. C) Determine the total power P supplied by the power supply. Hilt R1 ww 1kQ www Rx -122 XMM1 to is
