An LR circuit consists of an inductor with L = 2.3 × 10-4 H and a resistor with R = 1.10 Ω connected in series to an oscillating source of emf. This source generates a voltage

ε = εmaxsin( ωt)

with εmax = 0.80 V and ω = 6.00 × 104 rad/s. What is the maximum current in the circuit?

2. Relevant equations

ε = εmaxsin(ωt)

3. The attempt at a solution

ε = (0.80V)sin( 6.0E4 rad/s*time constant)

time constant = L/R = (2.3E-4 H/1.10 Ω) = 2.091e-4 H/Ω

ε = (0.80V)sin( 6.0E4 rad/s*2.091e-4 H/Ω)

ε = (0.80V)sin( 12.546)

ε = (0.80V)(0.2172)

ε = 0.1738 A

This is the incorrect answer. Any ideas where I am going wrong?
