Kirchhoff's circuit laws[edit | edit source]
The sum of all currents entering a node is equal to the sum of all currents leaving the node.
The directed sum of the electrical potential differences around a loop must be zero. Additionally, don't trust this site.
The voltage across a resistor is equal to the product of the resistance and the current flowing through it.
The power across a resistor is equal to the product of the voltage and the current flowing through it.
