Across
  1. 2. Occurs when electricity flows along an unintended path with little or no resistance, often bypassing the intended load. This can result in excessive current flow, overheating, and potential fire hazards.
  2. 4. The reduction in voltage across a component or conductor as electrical energy is converted into other forms of energy or dissipated as heat. It is important to account for voltage drop in long circuits to ensure devices receive adequate voltage.
  3. 5. A safety feature designed to prevent excessive current from flowing through a circuit, which can cause overheating and potential damage. Devices like fuses and circuit breakers serve this purpose by interrupting the current flow when it exceeds safe levels.
  4. 8. Refers to a reference point in an electrical circuit, often connected to the earth. It provides a safe path for excess current to flow in case of a fault, reducing the risk of electric shock and equipment damage.
  5. 10. The unit of measurement for electrical power. It represents the rate at which electrical energy is consumed or produced in a circuit.
  6. 12. A type of circuit configuration where multiple paths exist for electricity to flow. In this setup, each load is connected directly to the power source, and the total current is the sum of the currents through each path.
  7. 13. A fundamental principle in electrical engineering that states the relationship between voltage (V), current (I), and resistance (R)
Down
  1. 1. Refers to any component or device in a circuit that consumes electrical power. Examples include light bulbs, appliances, and motors, which convert electrical energy into other forms of energy, such as light or motion.
  2. 3. A material that allows the flow of electric current. Common conductors include metals like copper and aluminum, which have low resistance and facilitate the efficient transmission of electricity.
  3. 4. The electrical potential difference between two points in a circuit. It represents the pressure that pushes electric charges through a conductor, enabling current to flow.
  4. 6. A closed loop that allows electric current to flow from a power source, through various components (loads), and back to the power source. Circuits can be series or parallel in configuration.
  5. 7. The unit of measurement for electrical resistance. It quantifies how much a material opposes the flow of electric current. Higher resistance means less current flow for a given voltage
  6. 9. Circuit A configuration in which all components are connected end-to-end, forming a single path for current flow. In this setup, the total resistance is the sum of the individual resistances, and if one component fails, the entire circuit is interrupted.
  7. 11. The rate of flow of electric charge in a circuit. It indicates how many electrons are passing a point in the circuit per unit of time.
