In a photoelectric emission experiment, the stopping potential for a given metal is 'V' volt, when radiation of wavelength 'λ' is used. If radiation of wavelength '2λ,' is used with the same metal, then the stopping potential (in volt) will be: [c = velocity of light, e = charge on electron, h = Planck's constant] [MHT-CET 2023]

An alternating voltage source is connected in series with a resistance R and an inductance L. If the potential drop across the resistance is 200 V and across the inductance is 150 V, then the applied voltage is:

A 1 µF condenser is charged to 50 V. The charging battery is then disconnected and a 10 mH coil is connected across the capacitor so that LC oscillations occur. What is the maximum current in the coil ? Assume that the circuit contains no resistance. The capacity of a pure capacitor is 1 F. In d.c. circuits, its effective resistance will be

In an a. c. circuit the instantaneous current and e.m.f. are represented as: I = I0 sin(ωt – π/6) and E = E0 sin(ωt + π /3) respectively. The voltage leads the current by
