Series Circuit Calculator

How to Use the Series Circuit Calculator

The Series Circuit Calculator is a handy tool designed to assist in calculating various values in a series circuit. By following the simple steps below, you’ll be able to effectively utilize this calculator for your electrical projects.

Step 1: Input Required Values

• Total Voltage (V): Enter the total voltage of the circuit. This value is mandatory and should be non-negative. Use the placeholder as a guide and enter the voltage accurately up to two decimal places.
• Resistance 1 (Ω): Provide the resistance value for the first resistor in ohms. This field is required and should be a non-negative number. You can input the resistance to two decimal places.
• Resistance 2 (Ω): Enter the resistance for the second resistor, similar to resistance 1. It’s essential that this value is filled as it is required for the calculations.
• Resistance 3 (Ω): This field is optional. If there’s a third resistor in the circuit, input the resistance value here. If not entered, the calculator will consider it as zero.

Step 2: Calculate Results

Once you have filled in all the necessary input values, click on the “Calculate” button to perform calculations. The calculator will provide you with the following results:

• Total Resistance (Ω): The sum of all resistances in the circuit. The formula used is resistance1 + resistance2 + (resistance3 || 0). The result is formatted to two decimal places with a unit of ohms.
• Circuit Current (A): Calculated using the formula voltage / totalResistance. It displays the circuit current in amperes up to three decimal places.
• Voltage Drop Across Resistors (V): Three separate values are provided for each resistor:
  • Voltage across R1: current * resistance1
  • Voltage across R2: current * resistance2
  • Voltage across R3: current * (resistance3 || 0)

  Each is formatted to two decimal places with a unit of volts.

• Power Dissipated in Resistors (W): Similarly, the power dissipation is shown for each resistor:
  • Power in R1: pow(current, 2) * resistance1
  • Power in R2: pow(current, 2) * resistance2
  • Power in R3: pow(current, 2) * (resistance3 || 0)

  This is displayed in watts and formatted to two decimal places.

• Total Power Dissipated (W): Calculated using voltage * current, providing the total power loss in the series circuit. This result is formatted to two decimals.

Step 3: Review and Use Results

The series of computations will allow you to analyze and understand the behavior of the circuit better. You can use these results to confirm if your circuit design will perform as expected, ensuring safe and efficient operation. Should you need to reevaluate the circuit with different values, simply change the input fields and recalculate.
