both correct

How do u know

1) You are correct. In a series circuit, each circuit element has the same current. So the answer is A) current.

2) You are also correct. If a resistor is added to a series circuit, the equivalent resistance increases. So the answer is A) increases.

To answer question 1, in a series circuit, each circuit element has the same current. This means that the amount of electric current flowing through each element is equal.

To arrive at this answer, you can consider the properties of a series circuit. In a series circuit, all the components are connected in a single path so that the same current flows through each component. This is because the current has only one path to flow through, and it encounters the same amount of resistance in each element. Therefore, the answer is A, current.

For question 2, if a resistor is added to a series circuit, the equivalent resistance increases.

To determine this, let's understand how resistance works in a series circuit. In a series circuit, the total resistance is equal to the sum of resistances of all individual components connected in series. This means that the resistance increases as you add more resistors in series.

So, when a resistor is added to a series circuit, the total resistance increases, leading to a higher overall resistance in the circuit. Therefore, the answer is A, increases.
