Electricity flows in a closed circuit. For current to flow, there must be a source of voltage (like a battery), a conductive path, and a load (like a lamp). The basic rule is Ohm's Law, which states that voltage = current x resistance. This means that to control the current in a circuit, you can alter the resistance or the voltage.

FAQs & Answers

  1. What is Ohm's Law? Ohm's Law is a fundamental rule in electricity stating that voltage equals current multiplied by resistance (V = I × R).
  2. What are the key components needed for electricity to flow? Electricity requires a voltage source, a conductive path, and a load such as a lamp or motor for current to flow in a closed circuit.
  3. How can I control the current in an electric circuit? Current can be controlled by changing the voltage supplied or by adjusting the resistance within the circuit.
