There are two input signals (voltages), Va and Vb which cannot be detached from the ground. Design the circuit with two operational amplifiers and five resistors to generate output voltage, Vout = - 2Va + 10Vb. Va

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons
