material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature - heating a wire increases ...

The humble current shunt is an excellent way to do just that. Ohm’s Law. To understand current, it’s important to understand Ohm’s Law, which defines the relationship between current ...

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, I, on the ...
