3.4 Grouping Capacitors
What is the aim of grouping several capacitors? Among the reasons to group capacitors, we highlight to achieve the required capacitance or the desired working voltage by connecting several capacitors together.
练习题
What is a primary purpose of grouping several capacitors together in a circuit?
A. To reduce the overall cost of the circuit
B. To achieve the required capacitance or desired working voltage
C. To increase the power consumption of the circuit
D. To decrease the physical size of components
An engineer needs a capacitor with a specific capacitance value that is not available as a single component. Which approach should the engineer take?
A. Abandon the circuit design and start over
B. Use a resistor instead of a capacitor
C. Group several capacitors together to achieve the required capacitance
D. Increase the voltage supply to compensate
Which of the following are valid reasons for grouping capacitors in electronic circuits?
A. To achieve the required capacitance
B. To achieve the desired working voltage
C. To reduce the circuit's resistance
D. To store more electrical charge using the relationship
Grouping capacitors can be used to achieve a desired working voltage that may not be obtainable with a single capacitor.
The only reason to group capacitors is to increase the total capacitance value.
Both resistors and capacitors can be grouped in series, parallel, or mixed configurations to achieve desired circuit characteristics.
The two main reasons to group capacitors are to achieve the required ___ or the desired working voltage.
Explain why an engineer might choose to group several smaller capacitors instead of using one large capacitor in a high-voltage application.
When grouping resistors, the primary goals typically involve achieving desired total resistance and power distribution. When grouping capacitors, what are the main purposes?
A. To achieve the required capacitance or the desired working voltage
B. To reduce the total capacitance and increase the charge storage
C. To increase power dissipation and reduce voltage rating
D. To decrease the dielectric permittivity and increase plate separation
If a circuit requires a capacitance value that is not available in a single capacitor, grouping multiple capacitors together can be used to achieve the required capacitance.
When a single capacitor cannot handle the voltage in a circuit, engineers group several capacitors together to achieve the desired ___ while also obtaining the required capacitance.
Which of the following statements correctly describe the reasons for grouping capacitors in electronic circuits?
A. To achieve a required capacitance value that may not be available in a single capacitor
B. To achieve a desired working voltage that exceeds the rating of individual capacitors
C. To remove DC current from electrical signals more effectively
D. To increase the power dissipation in the circuit
