$2$b$.$ We can limit the diode current by adding a series resistor as shown below. Calculate the value of this additional resistor $R_S$ to limit current to a maximum value of $1$ A $($so that average current will be

$($Although a minor effect, don't neglect the existing $28\mathrm{.}6m).$

$2.$c$.$ Reconstruct the circuits above in the Falstad circuit simulator. Use the built$-$in model for the $1$N$4004$ diode. Omit the $28\mathrm{.}6m$ resistor from the simulation. It is built into the $1$ N $4004$ model. Report the maximum currents in your simulation and ensure they are within $5\%$ of your calculated answers.
