Problem

If the resistance in a series RLC circuit is increased while the inductance and capacitance remain unchanged, how will the resonance curve of current amplitude versus frequency be affected? (a)

I_{\max}

decreases and the resonance curve becomes sharper. (b) The resonance curve remains essentially unchanged because resonance depends only on

L

and

C

. (c)

I_{\max}

decreases and the resonance curve becomes broader. (d)

I_{\max}

increases and the resonance curve becomes broader.
