Instantaneous displacement current of 1.0A in the space between the parallel plates of 1μF capacitor can be established by changing the potential difference of:

A beaker is a field with water (μ=\(\frac{4}{3}\)) up to a height of 33.25cm. A concave mirror is placed 15 cm above the water level and the image of an object placed at the bottom is formed 25cm below the water level. The focal length of the mirror is nearly :

What is the r.m.s value of an alternating current which when passed through a resistor produces heat, which is four times that produced by a current of 2A in the same resistor?

An air doubble is inside water (μ=\(\frac{4}{3}\)). At what distance from the air bubble should a point object be placed so as to form a real image at the same distance from the dubble? (r is the radius of curvature of the bubble)

An r.m.s voltage of 220 V is applied across a series circuit having a resistance of 100 ohm and an impedance of 22 ohm. the power consumed is:
