What is the primary function of a capacitor?

• To convert AC to DC

• To generate electrical energy

• To store electrical energy

• To resist electrical current

What is the unit of capacitance?

• Ohm

• Farad

• Volt

• Watt

Which factor does NOT affect capacitance?

• Color of the capacitor

• Type of dielectric material

• Distance between plates

• Area of plates

What happens to capacitance if the distance between the plates is decreased?

• Capacitance becomes zero

• Capacitance increases

• Capacitance remains the same

• Capacitance decreases

Which of the following is a common dielectric material?

• Iron

• Copper

• Glass

• Aluminum

What is the dielectric constant?

• A measure of a material's conductivity

• A property that quantifies a dielectric material's effect on capacitance

• A measure of a material's resistance

• A measure of a material's temperature rating

What type of capacitor is typically used in power supply circuits?

• Ceramic Capacitor

• Supercapacitor

• Film Capacitor

• Electrolytic Capacitor

What is a key safety consideration when using capacitors?

• They are immune to temperature changes

• They can retain a charge even when power is off

• They do not need to be discharged

• They can be used in any circuit

Which application is NOT typically associated with capacitors?

• Power supply stability

• Signal amplification

• Energy storage

• Voltage regulation

What is the effect of inserting a dielectric into a capacitor?

• It increases the electric field

• It reduces the capacitance

• It decreases the charge stored

• It allows more charge to accumulate for the same voltage
