Using this analogy, let's now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher. Let's define this resistance as 2 ohms. The amount of water in the tank is the same as the other tank, so, using Ohm's Law, our equation for the...
The nominal impedanceZ= 4, 8, and 16 ohms (loudspeakers) is often assumed as resistanceR. Ohm's law equation (formula):V=I×Rand the power law equation (formula):P = I×V. P= power,IorJ= Latin: influare, international ampere, or intensity andR= resistance. ...
The aging myopathy manifests itself with diastolic dysfunction and preserved ejection fraction. We raised the possibility that, in a mouse model of physiological aging, defects in electromechanical properties of cardiomyocytes are important determinants
The amplitudes and temporal characteristics of both SEJPs and fast EJCs are predicted by the theory, but those of the slow EJCs are not. It is shown that these slow components cannot arise as a consequence of propagation of fast quantal components from their site of origin in the muscle ...
The dependencies of the critical current on temperature \(I_c (T)\) and of the amplitudes of the first current steps of the current–voltage characteristic \(i_n^{exp} (\sqrt{P})\) \((n = 0, 1, 2)\) on the power of microwave radiation with frequency \(f = (1.5 \div 8)\...
Transformer diagram 2-1 Figure 2-1 is a single-phase transformer structure, we can write the no-load voltage of the primary winding of the equation Where N1, R1, respectively, for the primary winding turns and the resistance (2.2) (2.1) can be rewritten as Where α t = 0, U1, such...
In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
a Zero-current switching and zero-voltage switching In resonant converters, the resonant block is present in the circuit in all topological stages. A great deal of energy is circulated in the resonance process. This is not acceptable in low- to medium-power converters. The quasi-resonant convert...
