Question 1

What is the relationship described by Ohm's Law?

Accepted Answer

Voltage = Current x Resistance

Answer

Ohm's Law states that Voltage (V) equals Current (I) multiplied by Resistance (R): V = IR.

Question 2

Which of the following materials is the best electrical conductor?

Accepted Answer

Copper

Answer

Copper is an excellent electrical conductor, which is why it is widely used in electrical wiring.

Question 3

What does a capacitor do in an electrical circuit?

Accepted Answer

Stores electrical energy in an electric field

Answer

A capacitor stores electrical energy in an electric field between two conductive plates separated by an insulating material.

Question 4

In a parallel circuit, what remains the same across all branches?

Accepted Answer

Voltage

Answer

In a parallel circuit, voltage is the same across all branches, while current divides among branches based on their resistance.

Question 5

What type of circuit is created when a wire accidentally connects two points that should not be connected?

Accepted Answer

Short circuit

Answer

A short circuit occurs when current bypasses the intended path through a low-resistance connection, potentially causing excessive current flow.
