What is the phase shift between total current and voltage in the circuit of a 100 ohm resistor connected in parallel with a capacitor that has a reactance of 100 ohm A. 180 degree B. 30 degree C. 45 degree D. 75 degree E. None of the above

The correct answer is $\boxed{\text{B) 30 degrees}}$.

In a parallel RLC circuit, the phase angle between the current and voltage is given by the following formula:

$$\phi = \arctan \left(\frac{X_C}{R}\right)$$

where $X_C$ is the capacitive reactance and $R$ is the resistance.

In this case, $X_C = R = 100\Omega$, so the phase angle is:

$$\phi = \arctan \left(\frac{100\Omega}{100\Omega}\right) = 30^\circ$$

The other options are incorrect because they do not represent the phase angle between the current and voltage in a parallel RLC circuit.
