The four basics of electricity are Voltage, Current, Resistance, and Power. Voltage (measured in volts) is the force that pushes electrons through a conductor. Current (measured in amps) is the flow of electrons. Resistance (measured in ohms) opposes the flow of current. Power (measured in watts) is the rate at which electrical energy is transferred by an electric circuit. Understanding these fundamentals is crucial for working safely with electrical systems.

FAQs & Answers

  1. What is voltage in electricity? Voltage is the force that pushes electrons through a conductor and is measured in volts.
  2. How does resistance affect electrical current? Resistance opposes the flow of electrical current, making it harder for electrons to pass through a conductor.
  3. What is the relationship between power and electricity? Power is the rate at which electrical energy is transferred in a circuit and is measured in watts.
