Question
Two resistors with the same resistance are connected in a 6-volt battery in series. What will happen to the total current across the circuit if another resistor of the same resistance is added considering the same voltage is applied?*1 pointIt will increase.It will decrease.It stays the same.It will increase, then decrease rapidly.
Solution
The total current across the circuit will decrease.
Here's why:
-
When resistors are connected in series, the total resistance of the circuit is the sum of the individual resistances.
-
If another resistor of the same resistance is added, the total resistance of the circuit increases.
-
According to Ohm's law, the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). So, I = V/R.
-
If the voltage remains the same and the resistance increases, the current will decrease.
So, the correct answer is "It will decrease."
