1. A circuit you built in bioelectrical lab has failed spectacularly. After admiring the fireworks, you notice that despite the voltage in the main circuit exceeding 100V, your arm, connected through an opamp buffer, does not seem affected. Why, and how might this differ if an inverting amplifier was used instead? (Consider both the case of your arm as an output and as an input).

2. Build a circuit to perform the calculation (2A-8B)dt Where A and B are two inputs, and you have access to 5V supplies and as many op-amps as you want.
