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

LEDs generate light, which is why they're in our screens. But if you instead shine a light on an LED, you can generate current to run a small device.

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.
