1002-B: Circuit Definitions 1: Multiple Choice

BACK to Ladder Voltage and Current Concepts

In this pod, we will learn the definitions of four quantities that determine how each electric circuit works: voltage, current, resistance, and power.

How hard an electron is pushed around a circuit by the battery.

What is slowing down electrons form moving around the circuit. The resistance in the circuit above is provided by the light bulb. All circuits must have resistance to be safe. A circuit with very low resistance is called short circuit, and is unsafe.

How fast charge moves around the circuit.

How fast the circuit converts energy from the battery to the output (the light bulb). Determines how bright the light bulb is.

Fill in the Blank

Word Bank:
  1. The resistance of a circuit is provided by the ____________________.
  2. The current tells you how fast the ____________________ is moving.
  3. If you have more power, the light bulb is ____________________.
  4. How fast the circuit converts energy from the potential energy battery to light is called the ____________________.
  5. How hard the electrons are being pushed is called the ____________________.
  6. To tell how fast charge is moving around the circuit, you need to know the ____________________.
  7. The voltage of a circuit is determined by the strength of the ____________________.
  8. What is blocking or slowing down electrons is called the ____________________.

True or False

  1. The resistance tells how fast the circuit converts energy.
  2. The current shows how fast neutrons are moving.
  3. The light bulb provides resistance to the circuit.
  4. The light bulb provides voltage to the circuit.
  5. The current shows how fast charges are moving.
  6. More current means the bulb will be less bright.
  7. The power tells how fast the circuit converts energy.
  8. The battery provides voltage to the circuit.
  9. More power means the bulb will be more bright.
