The insulating layer of a cacitor is called the 

• plate
• conductors
• dielectric
• terminals

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

• It's capacity C=Q/V
• the plate area
• the dielectric thickness
• all of the above

A charged capacitor act like 

• a DC open
• a momentary open
• a inverse voltage
• a current source

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

Capacitance is inversely proportional to 

• a charge
• dielectric thickness 
• plate area
• applied voltage

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
