Two capacitors, a 20 μ F and a 30 μ F, are connected in series. What is the total capacitance?
A) 12 μ F
B) 50 μ F
Series Connection
A method of connecting electrical components end-to-end, so the same current flows through each component.
Total Capacitance
The sum of individual capacitances in a circuit when connected in parallel, reducing when capacitors are in series, affecting the circuit's ability to store charge.
μ F
Microfarads, a unit of capacitance equal to one millionth of a farad.

Final Answer :
A
Explanation :
When capacitors are connected in series, the total capacitance is less than the smallest individual capacitor. The formula for total capacitance (C_total) in series is 1/C_total = 1/C1 + 1/C2. For a 20 μF and a 30 μF capacitor, 1/C_total = 1/20 + 1/30 = 1/12, so C_total = 12 μF.
