Question Ohms Law states the voltage drop across each resistor (R1 thru R3) is equal to its resistance amount times the current flowing through it. Based on this fact, calculate the voltage drop (V1 thru V3) across each resistor and select the answer containing correct voltage drops below. Please note: the current flow in this circuit was measured at It = 1mA 10 3.30 47

6. What is the benefit of low output impedance? A. Increase power consumption for maximum power transfer to the load B. Increase the voltage divider effect C. Decrease power consumption due to power loss D. Decrease the voltage divider effect 7. When an op-amp is operated in the single-ended differential mode, A. the output is grounded Bone input is grounded and a signal is applied to the other C. both inputs are connected together D. the output is not inverted 8. In the double-ended differential mode, A. a signal is applied between the two inputs B. the gain is 1 C. the outputs are different amplitudes D. only one supply voltage is used 9. In the common mode, A. Both inputs are grounded B. The outputs are connected together C. An identical signal appears on both inputs D. The output signals are in-phase 10. As the gain of the OP-AMP decrease, what happens to the bandwidth of it? A. Increase B. Decrease C. Nothing change D. None of the Above
