Diferential Equations, pls dont skip steps on the integrals and everything thank you A 12 volt battery is connected to a series circuit in which the inductor is 12 henry and the resistance is 10 ohms. Determine the current i, if the initial current is zero.
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 500 ohms and the capacitance is 10^-12 F (1 picofarad, pF. If the capacitor is initially uncharged and the transmitting gate changes instantaneously from 0 to 6 V, how long will it take for the voltage at the receiving gate to reach 5 V?
