Question

Initially, a single capacitance C1 is wired to a battery. Then capacitor C2 is added in series. Let C12 be the equivalent capacitance of C1 and C2. Which of these statements are true? (Select all that apply.)

Initially, a single capacitance C1 is wired to a battery. Then capacitor C2 is added in series. Let C12 be the equivalent capacitance of C1 and C2. Which of these statements are true? (Select all that apply.) The potential difference across C1 increases.The potential difference across C1 decreases.The potential difference across C1 remains the same.The charge on C1 increases.The charge on C1 decreases.The charge on C1 remains the same.C12 > C1C12 charge stored previously on C1charge stored on C1 and C2 together

Explanation / Answer

Here , When connected in series

1/Cseries = 1/C1 + 1/C2

Now , the true statements are :

The potential difference across C1 decreases

The charge on C1 decreases

charge stored on C1 and C2 together < charge stored previously on C1
