Question

The voltage across a resistor, an inductor, and a capacitor connected in series to an ac source are 20 V, 15 V and 30 V respectively. The resultant voltage in the circuit is ______.

Options

• 5 V

• 20 V

• 25 V

• 65 V

Answer 1

The voltage across a resistor, an inductor, and a capacitor connected in series to an ac source are 20 V, 15 V and 30 V respectively. The resultant voltage in the circuit is 65 V.

Explanation:

Resultant voltage in the circuit is the algebraic sum of all the voltages i.e. 
20 V + 15 V + 30 V = 65 V
