question 13

Multiple Choice

In a sinusoidally driven series RLC circuit, the inductive resistance is X_L = 200 $\Omega$ , the capacitive reactance is X_C = 100 $\Omega$ , and the resistance is R = 50 $\Omega$ .The current and applied emf would be in phase if:

• A)the resistance is increased to 100 \(\Omega\), with no other changes
• B)the resistance is increased to 200 \(\Omega\), with no other changes
• C)the inductance is reduced to zero, with no other changes
• D)the capacitance is doubled, with no other changes
• E)the capacitance is halved, with no other changes
