Determining power of independent voltage and current sources. Passive sign and active sign conventions are used to find out which source is supplyingpower and which one is absorbing.
Two simple circuits are used to demonstrate the characteristic of voltage and current sources. In both cases, the voltage sources are in series with current sources.
Five circuits are considered to explain the characteristics of voltage and current sources. It is shown how voltage sources enforce their voltages on parallel elements.
Finding the number of elements, nodes, loops and branches of a circuit
Determine the resistance of the resistor, and .
Finding power and conductance of resistors from the current and resistance
Finding the power of elements and determining which one is supplying power and which one is absorbing it.
