Problem 5.5 6 of 8 Review Figure1 of 1 The figure shows an operational amplifier, three resistors, and an independent current source. The amplifier has a positive supply voltage of 6 volts and a negative supply voltage of minus 6 volts. Current source I s with the current direction toward the amplifier is connected between the inverting input terminal and the common node. A 10-kiloohm resistor is connected between the output terminal and the inverting input terminal. The non-inverting input terminal is connected to the common node. A 2.5-kiloohm resistor and a 5-kiloohm resistor are connected in parallel between the output terminal and the common node. Current I subscript o flows through the 5-kiloohm resistor in the reference direction indicated towards the common node.
Part A Find io i o in the circuit in (Figure 1), given that ig i g = 0.50 mA m A . Assume the op amp is ideal. Express your answer to three significant figures and include the appropriate units.
