How to solve resistance in series?
i) Circuit Connection
Connect the resistors in series by placing them end to end, one to other. In a series circuit, the current passes through one resistor before flowing through the next. Connect the wires and battery for potential differences.
ii) Calculate Total Resistance
To calculate the total resistance (RT) in the series circuit, add the individual resistance values together:
RT = R1 + R2
RT = 100Ω + 150Ω
RT = 250Ω
iii) Apply Ohm’s Law Using Ohm’s law (V = I * R), you can find the current (I) flowing through the circuit. For this example, let’s assume the applied voltage is 12V.
I = V / RT
I = 12V / 250Ω
I = 0.048A or 48mA
vi) Voltage Drop In a series circuit, the voltage drops across each component add up to the total applied voltage.
Voltage Drop across R1 = I * R1 Voltage Drop across
R1 = 0.048A * 100Ω
= 4.8V
Voltage Drop across R2 = I * R2 Voltage Drop across
R2 = 0.048A * 150Ω
= 7.2V
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.
