Understanding Capacitors and Circuit Dynamics

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

• To convert AC to DC

• To store electrical energy

• To increase current flow

• To generate electricity

What happens when a capacitor is fully charged?

• It explodes

• It maintains a potential difference across its plates

• It starts discharging automatically

• It stops storing energy

Why does the iron wire explode when the capacitor discharges?

• Because it has low resistance

• Because it is made of copper

• Because it is too thick

• Because it cannot handle the high current

What is the role of resistance in the iron wire during the discharge?

• It increases the current flow

• It reduces the voltage

• It causes energy to dissipate as heat

• It prevents the wire from exploding

How does the copper bar prevent explosion during the final discharge?

• By having a smaller cross-sectional area

• By having higher resistance

• By dissipating energy more effectively

• By being a better conductor than the capacitor
