Kirchhoff's loop rule states that the algebraic sum of potential differences, including voltage supplied by the voltage sources and resistive elements, in any loop must be equal to zero. For example, consider a simple loop with no junctions, as in Figure 10.4.3. Figure 10.4.3: A simple loop with no junctions.
In a closed loop, whatever energy is supplied by a voltage source, the energy must be transferred into other forms by the devices in the loop, since there are no other ways in which energy can be transferred into or out of the circuit.
In a steady state, ideal capacitors draw no current. But if a circuit is assembled and switched on, one will observe that it take time for the capacitor to receive its full charge. Key: since capacitors accumulate a charge Q, the resistors in series with them carry a current I = dQ/dt.
The power supplied equals the power dissipated by the resistors and consumed by the battery V1. When using Kirchhoff's laws, you need to decide which loops to use and the direction of current flow through each loop. In analyzing the circuit in Example 10.4.2, the direction of current flow was chosen to be clockwise, from point a to point b.
