Comprehensive Electricity Quiz for 10th Grade

What is the fundamental unit of electric charge?

• Ampere
• Volt
• Coulomb
• Ohm

In a metal conductor, electric current is primarily due to the movement of:

• Protons
• Neutrons
• Electrons
• Ions

The formula for current (I) is:

• I = Q × t
• I = Q ÷ t
• I = V ÷ R
• I = P ÷ V

An ammeter is connected to a circuit:

• In parallel
• In series
• Diagonally
• Randomly

Potential difference is measured in:

• Amperes
• Watts
• Volts
• Ohms

In a solution, electric current can be carried by:

• Electrons
• Protons
• Ions
• Neutrons

Ohm's Law states that V =:

• I + R
• I × R
• I ÷ R
• R ÷ I

A thermistor's resistance:

• Remains constant
• Decreases with temperature
• Increases with temperature
• Fluctuates randomly

In a series circuit, the current through each component is:

• Different
• Zero
• The same
• Randomly distributed

In a parallel circuit, the potential difference across each branch is:

• Increasing
• Decreasing
• Constant
• Variable
