A single element like a resistor
What does Kirchhoff's Current Law (KCL) state?
The total current is equal to the voltage divided by resistance
The total resistance in series is the sum of resistances
The sum of currents entering a node is zero
The sum of voltages in a loop is zero
What is the equivalent resistance of resistors in series?
The sum of the individual resistances
The product of the resistances
The maximum resistance
