In a series circuit, how will the voltage drop across each resistance behave?

In a series circuit, the voltage drop across each resistor is determined by Ohm's Law, which states that the voltage across a resistor is directly proportional to the current flowing through it and its resistance (V = IR). Since the same current flows through all components in a series circuit, the total voltage provided by the power source is distributed among the resistors.

As each resistor has its own resistance, the voltage drop across each one will vary based on their individual resistance values. However, the sum of all the voltage drops across the resistors will equal the total voltage supplied by the source. This is because the energy supplied by the source is converted into heat energy in the resistors, adhering to the law of conservation of energy.

Therefore, the correct conclusion is that the voltage drops across each individual resistance in a series circuit will add up to equal the source voltage. This understanding is crucial for analyzing and designing series circuits in HVAC systems and other electrical applications.
