A 120 Ω resistor is in parallel with a capacitor with a capacitive reactance of 40Ω. Both components are across a 20 V AC source. What is the magnitude of the total current through the circuit?
1
\(\sqrt {\frac{1}{{120}}} A\)
2
\(\sqrt {\frac{2}{{9}}} A\)
3
\(\sqrt {\frac{1}{{40}}} A\)
4
\(\sqrt {\frac{5}{{18}}} A\)
