An average-reading digital multimeter reads 10 V when fed with a triangular wave, symmetric about the time-axis. For the same input an rmsreading meter will read

Correct Option: A
| VAV = | × Vmax × | ||
| 2 | 2 | = 10 | |
| 2 | |||
∴ Vmax = 10 × 2 = 20V
Equation of line OA, υ = mt
| At t = | , υ = 20 | |
| 4 |
| ∴ m = | = | |||
| T / 4 | T |
| ⇒ υ = | t | |
| T |
