WebbFrom there you have a simple circuit with a resistor and an open. Should be easy to simplify then. If you have an open in the circuit, then all of the voltage drops across the open and you have no current flow. If you have a complete circuit (no opens), then you have the current flowing through resistors according to Kirchhoff's law and Ohm's law. WebbBoth AC and DC circuits can be solved and simplified by using these simple laws which are known as Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL).
