Voltage Calculation for Series Capacitors

What is the key principle regarding the sum of potential differences across capacitors in series?

• It is always zero.

• It equals the voltage of the battery.

• It is twice the voltage of the battery.

• It is half the voltage of the battery.

Which equation is used to calculate the potential difference across a capacitor?

• V = I * R

• Q = C * V

• P = V * I

• E = Q * V

What is the rule for charge on capacitors in series?

• The charge is equal to the capacitance.

• All capacitors have the same charge.

• The charge is zero.

• Each capacitor has a different charge.

How is the potential difference across a capacitor calculated using its charge and capacitance?

• By subtracting capacitance from charge.

• By dividing charge by capacitance.

• By multiplying charge and capacitance.

• By adding charge and capacitance.

What is the potential difference across the first capacitor if the charge is 26.6 kum and the capacitance is 12?

• 12 volts

• 5.33 volts

• 4.4 volts

• 2.23 volts
