The shown parallel circuit has L=1 H,C=1 F,R=2 Ω and current source I=sin(t) A. It is in sinusoidal steady state. Find v at t=π/2 s, in volts to two decimals.
At angular frequency one radian per second, inductive admittance is −j and capacitive admittance +j, cancelling exactly. Only resistor admittance 1/2 remains, so voltage is v(t)=2sin(t) V. At π/2 this is 2.00 V.
