STEP2 ON Circuit

Question

Create a circuit where the white lamp is turned on by pressing BS1 (switch 1), and is turned off by releasing.

Hint

Add BS1 and the white lamp to the circuit diagram created in STEP1. An alternating current of 100 V (100 V AC), which is commonly used in households, is applied to the lines on the left and right. Between those lines, arrange the switch and white lamp side by side and connect them with lines. The connecting lines represent wiring cables to be actually routed for wring.

It is easy to understand in a diagram, but hard to understand in a text. Thus, circuit diagrams are used.

Key point

In this step, the switch is used for the first time. The video above explains that the switch has the a-contact (normal open) and b-contact (normal close). The switch is used to turn on and off the current.

The switch used here is also used in machine tools and others. Switches also have ratings. Check them on the internet when you have time.

Devices to use

  • Circuit breaker
  • Red lamp (C2)
  • Fuse (enclosed type, 5 A)
  • Terminal block
  • Switch 1 (BS1)
  • White lamp (C9)
