V1 is the voltage across resistor 1, while V2 is the voltage across resistor 2. When connected in series, the battery voltages add together. The total voltage (battery voltage) equals V1 plus V2. This series connection raises the overall voltage in the circuit, affecting the current output capacity and electrical resistance.
The battery voltage, or the total voltage supplied by the battery, influences both V1 and V2. When a circuit is analyzed, the sum of all voltage drops (including V1 and V2) should equal the battery voltage. This principle stems from Kirchhoff’s Voltage Law, which states that the total of all potential differences in a closed loop equals zero.
In practice, if V1 increases, V2 may decrease if the battery voltage remains constant, illustrating the interdependence of these voltage points. Moreover, understanding these relationships helps in designing circuits and troubleshooting issues.
