The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

To determine the voltage, current and resistance of an electric circuit. Ohm's law can be used to calculate the power dissipated in a circuit. In circuits with multiple components, it is important ...

For each pair of results calculate the resistance, R using \(R = \frac{V}{I}\). Record your results in the third column of the table. Plot a graph of voltage, V on the y-axis v current ...
