MCQ 15_Capacitor and Capacitance

------------------------ is created out of two metal plates and an insulating material called a dielectric.

• An inductor
• A capacitor
• A fixed resistor
• A variable resistor

With respect to the capacitor, which relationship is true?

• C = Q/V
• V = C×Q
• Q = C/V
• Q = V/C

amount of charge stored per unit volt

• capacitance
• capacitor
• dielectric
• dielectric constant

device that stores electrical charge and electrical energy

• capacitance
• capacitor
• dielectric
• dielectric constant

What is the voltage across   the plates of the capacitor if  the capacitance is 10 uF and the Charge stored is  30 uC?

• 0.333 V
• 3 V
• 300 V

A capacitor of capacitance 30μF is fully charged from a 10 V d.c. supply. Calculate the charged stored by the capacitor

• 3.0 mC

• 0.30 mC

• 300 mC

• 330 kC
