For the circuit, assuming an ideal op amp, and given Vs = - 1.5 V, R1 = 1 K ohm, R2 = 15k ohm, and R3 = 5k ohm, answer the following question. (Annotate diagram to show branches and nodes.) (a) Find the currents in all the branches (b) Find the voltages at all nodes  (c) Find the power dissipated in each resistor (a) Find the total power dissipated in all resistors (e) How much power is delivered by Vs? (f) Explain: where does the rest of the power come from?

NEED IN RUSH!THANKS IN ADVANCE

Consider two points at different voltages, and v₂. Design a circuit using an operational amplifier and some resistors for which the output voltage of the op-amp would be defined by the following equation: Vout = 2v₁ +0,5v₁₂

In an Op-Amp Differential Amplifier, how should I find R1 and R4 when V1, V2, VOUT, and IR1 are given? Hint: R1 = R3, and R2 = R4
