Understanding Capacitors and Circuits

What is the primary function of a capacitor in a circuit?

• To store electrical energy

• To generate electricity

• To increase resistance

• To convert AC to DC

What happens when a switch is flipped in a circuit containing a charged capacitor?

• The capacitor starts charging

• The capacitor discharges slowly

• The circuit remains open

• Electrons flow from the negative to the positive plate

Which law explains the relationship between voltage, current, and resistance?

• Coulomb's Law

• Faraday's Law

• Newton's Law

• Ohm's Law

Why does a wire explode when a high current flows through it?

• The wire is made of copper

• The wire has high resistance

• The wire is too long

• The wire cannot dissipate the heat generated

How does a copper bar help in discharging a capacitor safely?

• It prevents electron flow

• It dissipates energy better due to higher resistance

• It increases the voltage

• It has a lower resistance than the wire
