In an LCR circuit shown in the following figure, what will be the readings of the voltmeter across the resistor and ammeter if an a.c. Source of 220 V and 100Hz is connected to it as shown?

Options

A. 800V, 8A
B. 110 V, 1.1 A
C. 300 V, 3A
D. 220V, 2.2 A

Answer

D

Explanation

In case of series RLC circuit, Equation of voltage is given by `V^(2) = V_(R)^(2) + (V_(L) - V_(C))^(2)`
Here, `V = 220 V, V_(L) = V_(C) = 300 V`
`therefore V_(R) = sqrtV^(2) = 220 V`
`"Current" i = (V)/(R) = (220)/(100) = 2.2 A`
