Electricity Quiz

What is the flow of electric charge called?

• electricity

• electricity flow

• electric current

• electricity movement

What is the unit of electric current?

What is the symbol for electric current?

• E

• I

• C

• V

What is the formula to calculate electric current?

• I = V + R

• I = V - R

• I = V x R

• I = V/R

What is the difference between series and parallel circuits?

• Series circuits have a higher total resistance compared to parallel circuits.

• The main difference between series and parallel circuits is the way the components are connected.

• Series circuits have components connected in a single loop, while parallel circuits have components connected in multiple branches.

• Series circuits have a lower total voltage compared to parallel circuits.

What is the formula to calculate resistance in a circuit?

• R = V/I

• R = V^2/I

• R = P/I

• R = I/V

What is the unit of electrical resistance?

• volt

• ampere

• watt

• ohm

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

• V = I^R

• V = I + R

• V = I * R

• V = I / R

What is the purpose of a fuse in a circuit?

• To protect the circuit from excessive current flow

• To regulate the temperature in the circuit

• To increase the voltage in the circuit

• To amplify the current in the circuit

What is the difference between AC and DC current?

• AC current flows faster than DC current.

• AC current flows in only one direction, while DC current periodically changes direction.

• AC current periodically changes direction, while DC current flows in only one direction.

• AC current and DC current are the same thing.
