Answer:
The current in the circuit isn't affected i.e it remains the same
Step-by-step explanation:
In a series connected circuit, same current flows across the resistors bit different voltage is passed across them. This means that no matter the value of the resistance in a series connected circuit, the current flowing through the resistors will remain the same.
Based on the above conclusion, if one of the resistors is replaced with a resistor having a lower resistance value in a series circuit, the current in the circuit will not be affected.
