Question : 47

Total: 65

From the diagram above, if the potential difference across the resistor, capacitor and inductor are 60V, 120V and 30V respectively, the effective potential difference is

Validate

Solution:

$V_L$ =60 V , $V_C$ = 120 V , $V_R$ =30V

;V = ?

V^2

30^2

60 - 120^2

V^2

= 900 + 3600

V^2

= 4500

= V = √4500 = 67V
