Question
Three resistors with the same resistance are connected in a 12-volt battery in a series circuit. If one resistor is removed, what will happen to the voltage that runs across the remaining resistors?*1 pointIt will increase.It will decrease.It stays the same.It will increase, then decrease rapidly.
Solution
The voltage that runs across the remaining resistors will increase.
Here's why:
-
In a series circuit, the total resistance is the sum of the individual resistances. So, if you have three resistors with the same resistance, the total resistance is three times the resistance of one resistor.
-
The voltage across each resistor in a series circuit is proportional to its resistance. So, when all three resistors are in the circuit, the 12-volt battery voltage is divided equally across the three resistors.
-
If one resistor is removed, the total resistance of the circuit decreases. This means that the same battery voltage is now divided across only two resistors instead of three.
-
Therefore, the voltage across each of the remaining resistors will increase.
