RC snubber circuit design and calculations for inductive loads

You should not switch inductive loads without some form of flyback or snubber protection.

Using simulations we identify the problem of using switches or relays to control inductive loads. We then see how to include an RC (resistor-capacitor) snubber circuit to absorb energy from the inductor and therefore reduce transient voltages. We then go through the calculations step-by-step to choose appropriate RC values for your circuit.

Note to my students: RC snubber circuits are not an examinable topic for GCE A level electronics but are a useful topic to be aware of, particularly if you plan to switch inductive loads (e.g. solenoids) in your project work. The video draws on some topics that appear may appear in GCE A level electronics and physics.
