Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...

A handy nomograph quickly determines the equivalent resistance of two parallel resistors. Although you could use the standard formula and a calculator, the nomograph also lets you easily find ...

Plot a graph of resistance, R, in Ω on the y-axis against length, l, in cm on the x-axis). Draw the line of best fit. We can see from the graph that as the length of the wire, l, increases, the ...
