What do series and parallel circuits have to do with Christmas ... Then, using Ohm's Law, you can calculate the voltage across, and current through, each resistor. OK, let's do the easiest steps ...

Ellie and James explore series and parallel circuits. They also discuss the differences between current and resistance across different circuits and how to calculate them. JAMES: Hello and welcome ...

What you’d like is a device that can source or sink a given amount of current regardless of the supply voltage. Remember, in a single loop circuit ... You can find my solution online.

It's pretty difficult to find that one bulb ... in a line so that the same current goes through each one. This is a series connection. The difference in this circuit is that each lightbulb has ...
