What is an electric circuit?

• A broken path for electric current

• A closed path in which an electric current travels

• A path with no electric current

• A path that only conducts heat

What unit is used to measure electric current?

• Ohms (Ω)

• Volts (V)

• Amperes (Amps)

• Joules (J)

What happens to electric current when resistance is increased?

• Current increases

• Current decreases

• Current remains the same

• Current fluctuates

What is the SI unit of electric voltage?

• Amps

• Volts

• Ohms

• Watts

According to Ohm's Law, what is the relationship between voltage (V), current (I), and resistance (R)?

• V = I + R

• V = I / R

• V = I * R

• V = R / I

What are the three main parts of an electric circuit?

• Battery, switch, and light bulb

• Energy source, wires, and device/load

• Resistor, capacitor, and inductor

• Generator, transformer, and motor

What is a characteristic of a series circuit?

• It has multiple paths for current to flow

• It is used mostly in homes

• If one part is broken, the whole circuit stops working

• It is used in high-voltage applications
