The probes of a non- isolated, two - channel oscilloscope are clipped to points A, B and C in the circuit of the figure given below. Vin is a square wave of a suitable low frequency. The display on Ch1 and Ch2 are as shown on the right. Then the “Signal” and “Ground” probes S1, G1 and S2, G2 of Ch1 and Ch2 respectively are connected to points
-
- A, B, C, A
- A, B, C, B
- C, B, A, B
- B, A, B, C
Correct Option: B
Here, B is a common point
| S1 | → | A |
| G1 | → | B |
| S2 | → | C |
| G2 | → | B |
Hence answer is A, B, C, B
