Total Voltage Formula:
| From: | To: |
In a series circuit, the total voltage is the sum of all individual voltage drops across each component. This follows Kirchhoff's Voltage Law, which states that the sum of all voltages around any closed loop in a circuit must equal zero.
The calculator uses the series voltage formula:
Where:
Explanation: In a series circuit, the same current flows through all components, and the voltage drops add up to equal the total applied voltage.
Details: Calculating total voltage is essential for circuit analysis, component selection, power supply design, and troubleshooting electrical systems. It helps ensure proper operation and prevents component damage.
Tips: Enter voltage values in volts. At least one voltage value is required. You can enter up to four voltage values for calculation. All values must be non-negative.
Q1: Why do voltages add up in series circuits?
A: According to Kirchhoff's Voltage Law, the sum of voltage drops around a closed loop equals the total applied voltage, conserving energy in the circuit.
Q2: What happens if components have different voltage ratings?
A: Components must be selected so that their voltage ratings exceed the actual voltage drops, otherwise they may fail or be damaged.
Q3: Can this calculator handle more than four voltages?
A: The current version supports up to four voltages. For more complex circuits, you may need to perform multiple calculations or use specialized software.
Q4: Does this work for AC circuits as well?
A: For AC circuits with purely resistive loads, yes. For reactive components (inductors, capacitors), phase angles must be considered using vector addition.
Q5: What units should I use for voltage?
A: The calculator uses volts (V) as the standard unit. Make sure all input values are in the same unit for accurate results.
