An electric dipole with dipole moment is in a uniform electric field. If the dipole is in the stable equilibrium state,which of the following statements is correct?A.The torque is zero and potential energy is minimum.B.The torque is zero and potential en
The influence of the nitrogen pressure on the breakdown voltage in a nonuniform electric field is studied. Voltage pulses with nanosecond and subnanosecond rise times are applied to the gas gap. Simultaneously with the application of voltage pulses, supershort avalanche electron beam pulses are obser...
