How to identify the resistances are connected in series?
In order to identify the resistance in series we have to observe the circuit carefully. Following are the thing that needs to be kept in mind in order to understand a series resistance:
- Physical Layout: In a series circuit, resistors are linked end-to-end, with current passing through each one sequentially. Tracing the circuit’s path and identifying its components can aid in recognizing the resistors in series.
- Resistance Measurement: We can identify using a multimeter we can measure the resistance of each resistor and then we can calculate their sum an check if it’s equal to the total resistance because in series total resistance is equal to R1 + R2…+ Rn.
- Ohm’s Law: In the case of the overall circuit voltage and total current are known, we can use ohms law V = I*R for determining the total resistance then subtracting known resistor values enables deduction of the remaining series resistors.
- Color Codes or Markings: If resistors have color bands denoting resistance values, a resistor color code chart can decode these values. Compare color bands to the chart to determine resistance. This approach might be unsuitable if resistors lack color bands or visibility.
- Voltage Drop: Measure voltage drops across each resistor using a multimeter. Because if we sum up all voltage drops then it will give the total applied voltage in series circuits, comparing drops helps identify series resistors.
Resistors in Series
Resistors are devices that obstruct the flow of electric current in the circuit. They provide the hindrance to the path of the current which flows in the circuit.
A resistor is a two-terminal electrical component that works by reducing the flow of charge and voltage levels in the circuit. Most of the circuits have one or more resistors to oppose the flow of current and balance the circuit. Most commonly there are two combinations of resistors – Resistors in Series and Parallel.
