From the diagram above, if the potential difference across the resistor, capacitor and inductor are 80 v, 110 v, 40 v respectively, the effective potential difference is?
- 116.3 V
- 50.0 V
- 230.0 V
-
106.3 V
The correct answer is: D
Explanation
V = √ \({(v_l - v_c)}^2 + V^2R\)
V =√ \({(40 - 110)}^2 + 80^2\)
V = √ \({-70}^2 + 80^2\)
=√ 4900 + 6400
=√ 11300
= 106.3v
