Electricity

What is the flow of electric charge in a closed path called?

• charge movement

• electric flow

• electric current

• circuit stream

What is the unit of electric current?

• Ampere (A)

• Volt

• Joule

• Ohm

In which direction does conventional current flow?

What happens to the brightness of a bulb when more bulbs are added in parallel?

• The brightness of the bulbs decreases.

• The brightness of the bulbs increases.

• The brightness of the bulbs remains the same.

• The brightness of the bulbs fluctuates.

What is the purpose of a switch in an electric circuit?

• To regulate the voltage

• To generate electricity

• To increase the resistance in the circuit

• To open or close the circuit

What is the formula to calculate electrical power?

• Power (P) = V x I

• Power (P) = V - I

• Power (P) = V + I

• Power (P) = V / I

What is the relationship between voltage, current, and resistance in a circuit?

• V = I ^ R

• V = I / R

• V = I * R

• V = I + R
