The potential differences across the resistance, capacitance and inductance are $80\text{V},40\text{V}$ and $100\text{V}$ respectively in an L-C-R circuit. The power factor of this circuit is:

A $100\Omega$ resistance and a capacitor of $100\Omega$ reactance are connected in series across a $220\text{V}$ source. When the capacitor is $50\%$ charged, the peak value of the displacement current is:

Two identical glass (${\mu }_g=3/2$) equiconvex lenses of focal length $f$ each are kept in contact. The space between the two lenses is filled with water (${\mu }_w=4/3$). The focal length of the combination is:

An air bubble in a glass slab with refractive index $1.5$ is $5\text{cm}$ deep when viewed from one surface and $3\text{cm}$ deep when viewed from the opposite face. The thickness (in cm) of the slab is:

The interference pattern is obtained with two coherent light sources of intensity ratio $n$. In the interference pattern, the ratio $\frac{I_{\text{max}}-I_{\text{min}}}{I_{\text{max}}+I_{\text{min}}}$ will be:
