- The pathway for a binary electrical signal between gates in an integrated circuit can be modeled as an RC circuit, as shown in the figure to the right; the voltage source models the transmitting gate, and the capacitor models the receiving gate. Suppose the resistance is 300 S2 and the capacitance is 10-11 F (10 picofarads, pF). If the capacitor is initially uncharged and the transmitting gate changes instantaneously from 0 to 4 V, how long will it take for the voltage at the receiving gate to reach 3 V? It will take seconds. (Use scientific notation. Round to three decimal places as needed.)
