Which of the following is accurate about Kirchhoff’s law?

The sum of the change in voltages around any closed path of a circuit adds to 0
The total voltages of all elements in a circuit adds to a total of 0
The total voltage of all batteries in a circuit add to 0
The sum of the change in voltage across all resistors in a circuit adds to 0
The total voltage across all junctions adds to 0

Resistors A and B are in parallel with each other. Resistor C is in series with the equivalent resistor of A and B. Which of the following is true of the relationship between resistors A and C?

There is no addition rule for just these 2 resistors alone
They are in series
They are in parallel
They are partly in series, partly in parallel
They are both relatively parallel with B

We are applying Kirchhoff’s law to a closed path in a circuit. As we go from the negative terminal of a battery to the positive terminal how will the voltage of the battery be taken into account?

The voltage of the battery will be added to the total voltage since we are going from the negative terminal of the battery which has a lower voltage to the positive terminal which has a higher voltage.
The voltage of the battery will be subtracted from the total voltage since there is a reduction in voltage as we go through a battery.
Their voltages are skipped and not taken into account.
Their voltages are multiplied by the current flowing through the battery.
Double the voltage of the battery is added to the total voltage.

A wire carrying current I splits into two wires carrying currents I₁ and I₂. Which of the following statements is true?
