About Simulation

  • Simulation of Ohm's Law is designed to verify the relationship between voltage, current, and resistance in an electrical circuit, providing a virtual platform for experimentation and understanding electrical principles.
  • Users can engage in interactive experiments to validate Ohm's Law by varying the voltage across a resistor and measuring the resulting current, or by changing the resistance while keeping voltage constant.
  • The simulation enables investigation into how changing parameters like voltage and resistance affect the current flow in the circuit, allowing for a deeper understanding of Ohm's Law.
  • Users can manipulate circuit elements such as resistor values, voltage sources, and connection configurations to observe the effects on voltage, current, and resistance.
  • Graphical representations of voltage, current, and resistance can be displayed in real-time, aiding in the visualization of Ohm's Law principles.

Physics Practical Class

  • The simulation provides a virtual laboratory environment where users can conduct experiments safely and conveniently, mimicking real-world electrical circuits.
  • Users encounter real-life scenarios where knowledge of Ohm's Law is applied, such as designing circuits, troubleshooting electrical problems, or optimizing power consumption.

1. Electric Cell/Battery
According to Ohm’s law, the potential difference (V) across the ends of a resistor is directly proportional to the current (I) through it, provided its temperature remains the same. That is,

Here, R is a constant for the given resistor at a given temperature and is called its resistance. The SI unit of resistance is ohm (Ω).

A graph between the potential difference across the two ends of a resistor and the current through it is a straight line passing through the origin. The slope of this graph gives the resistance R of the resistor.

To verify Ohm’s law, we measure the potential difference across the two ends of a resistor at different currents through it in an electric circuit. The current through the resistor is measured by connecting an ammeter in series with it. The potential difference across the two ends of the resistor is measured by connecting the voltmeter in parallel with it.
