Capacitance

A Capacitor

• provide a specific value of capacitance
• stores energy in a electrostatic field 
• opposes any change in voltage
• all of the above

The amount of charge that a capacitor can accept is determined by

• It's capacity C=Q/V

• the plate area

• voltage

• all of the above

A capacitor needs which source?

• Direct Current (DC)

• Alternating current (AC)

• Both

The two leads of the capacitor are connect to the 

• plates
• terminals
• conductors
• dielectric

When a capacitor discharges

• current reverses direction compared to the charge current
• it acts like a DC open
• the electrostatic charge remains 
• plate voltage increases

Capacitors well hold a charge until

• the applied voltage drops to zero
• 5 time constants
• an external discharge path is provided
• 1 time constant

Connecting capacitors in parallel effectively causes the _____ ________

• distance between the plates , increase

• distance between the plates , decrease

• plate area increase

• plate area decrease

Connecting capacitors in series effectively causes the _____ ________

• distance between the plates , increase

• distance between the plates , decrease

• plate area increase

• plate area decrease

The capacitance of a parallel-plate capacitor can be increased by: 

• increasing the charge 
• decreasing the charge 
• increasing the plate separation
• decreasing the plate separation 

In the capacitor, the dielectric can be made out of all sorts of ---------- materials and the plates are made of a -------------- material.

• conductive, insulating 
• conductive, conductive
• insulating, conductive
• insulating, insulating
