Performance of dissipative dielectric elastomer generators
... elastomer actuators.16 We first show that conversion cycles in DEGs reach steady-state conditions after several cycles. This allows us to represent cycles in work conjugate plots. We then introduce performance parameters of DEGs: electrical energy generated per cycle, average power output, and mecha ...

... Paramagnetism is the behavior of those materials that exhibit a permanent magnetic dipole moment. They also include an unpaired electron shell usually in the 3d or 4f shells [2, 3]. Various theories of paramagnetism are presented which are true for certain kinds of materials. For example, the Langev ...

Questions Question 1 Explain why transformers are used
... If we wrap a second coil of wire around the same magnetic core as the first (inductor) coil, we set up a situation where mutual inductance exists: a change of current through one coil induces a voltage in the other, and visa-versa. This, obviously, will result in an AC voltage being induced in the s ...
