We use a V.I.R. chart to help us solve series, parallel, and complex circuits problems. In this Closer Look segment on circuits, we use a V.I.R. chart to help us solve series, parallel, and complex ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...
