Question:
Consider the 741 op-amp in Figure 13.3, biased with \(V^{+}=15 \mathrm{~V}\) and \(V^{-}=-15 \mathrm{~V}\). Assume that no load is connected at the output, and let the input voltages be zero. Calculate the total power dissipated in the op-amp circuit. What are the currents supplied by \(V^{+}\)and \(V^{-}\)?
