Direction: Statement for Q. 103 to Q. 105. A signal generator supplies a sine wave of 20V, 5kHz to the circuit shown below—
-
Calculate total current IT—
-
- 0·24 ∠ 33°
- 2·4 ∠ 33°
- 24 ∠ 30°
- None of these
- 0·24 ∠ 33°
Correct Option: A
The given circuit: 
Capacitive reactance,
| XC = | = | ||
| 2πfC | 6·28 × 5 × 103 × 0·2 × 10–6 |
= 159·2Ω
| IR = | = | = 0·2A | ||
| R | 100 |
| IR = | = | = 0·126A | ||
| XC | 159·2 |
The total current (IT) in parallel circuit is the vector sum of the branch currents. i.e.
IT = IC.IR + j IC = (0·2 + j 0·126)A
or
IT = 0·24 33°
