Understanding Circuits and Ohm's Law

What do the principles of an electrical circuit govern?

• Color of wires

• Flow of electric charge and behavior of components

• Size of components

• Temperature of the circuit

In what unit is electric current measured?

• Volts (V)

• Ohms (Ω)

• Amperes (A)

• Watts (W)

According to the principle mentioned, what happens when the voltage is greater?

• The potential energy decreases

• The potential energy remains the same

• The potential energy increases

• The potential energy is unaffected

Which of the following is NOT a characteristic of voltage?

• Measured in volts

• Acts as a force

• Difference in electric potential energy

• Measured in amperes

Which of the following best describes voltage?

• A measure of resistance

• A measure of electric potential difference

• A measure of power

What is the principle related to voltage mentioned in the document?

• Voltage decreases potential energy

• Voltage has no effect on potential energy

• Greater voltage means greater potential energy

• Greater voltage means lesser potential energy

What is the symbol for current?

• V

• R

• Viscosity

What happens to the power if the voltage in a circuit is doubled while the current remains constant?

• Power is halved.

• Power remains the same.

• Power is doubled.

• Power is quadrupled.
