Understanding Equivalent Capacitance in Series

What is the voltage supply used in the example circuit?

• 9 volts

• 24 volts

• 12 volts

• 15 volts

Which formula is used to calculate the equivalent capacitance for capacitors in series?

• C_eq = (C1 + C2 + C3) / 3

• C_eq = C1 * C2 * C3

• 1/C_eq = 1/C1 + 1/C2 + 1/C3

• C_eq = C1 + C2 + C3

What is the first step in calculating the equivalent capacitance for capacitors in series?

• Multiply the capacitances

• Divide the capacitances

• Add the capacitances directly

• Use the reciprocal formula

What is the equivalent capacitance of the circuit in the example?

• 0.45 farads

• 2.22 farads

• 12 farads

• 5 farads

Why can't you simply add the capacitances of capacitors in series?

• Because it would result in a higher capacitance

• Because they are in parallel

• Because the voltage is too high

• Because the reciprocal method must be used
