Question

12.
The reading of ammeter in the circuit is
(1) 2A
(2) 3'A
(3) Zero
(4) 1 A
​

Answer 1

Answer:

1

Explanation:

first you should know,

only resistance offered by resistance exist in same phase

while,resistance offered by capacitor (lag)and inductor (lead)are lag and lead the phase by 90° respectively.

so,here vector sum will apply .

X(c) and X (l) are in opposite phase and have same value,so it cancells each other.

resistance in loop is only carried out by resistor(55ohm)

so,,. I=v/r

i =110/55=2amp
