Two drivers in parallel provide twice as much current and split power loss into two locations, which makes for easier heat dissipation.

Here are a bunch of LEDs connected in parallel such that the current from each LED adds to the total current. This LED bank is connected to a solar power calculator with the solar cell removed.

If you perform analog-circuit design, you'll occasionally need to use a resistor with a nonstandard value to produce a particular gain, ratio, or attenuation factor. You can create resistors of ...

In National 4 Physics learn how the operation of switches and variable resistors allow us to control real circuits in the appliances around us.
