This is especially true if gases are evolved in the electrolysis process. What is the reason for this? The gases produced stay on the surface of the electrodes, and behave like an electrochemical cell to produce an emf that opposes the electrolysis process.Electrolysis...
Forum: Introductory Physics Homework Help S ODE of an electric circuit consisting of EMF source, inductor and capacitor (a) $$\varepsilon (t)=V_L+V_C$$ $$\varepsilon (t)=L\frac{dI}{dt}+\frac{q(t)}{C}$$ $$\varepsilon (t)=L\frac{d^2 q}{dt}+\frac{q(t)}{C}$$ (...
Homework Statement An inductor with L = 50 mH is in series with a resistor of R = 180 ohms. At t = 0, a potential difference of 45 V is suddenly applied across the series circuit. At what rate is the current increasing after 1.2 milliseconds? Homework Equations V = IR + Emf Emf =...
variation of the induced emf as the magnet is moved. Eddy currents are created when a conductor moves through a magnetic field or when the magnetic field surrounding a stationary conductor changes, that is, anything that causes the magnetic field around the conductor to change in intensity or ...
Clearly, the commu- nity around the language is a key element in the process. We call community the group of people involved with the DSML under development, which includes both technical level users (i.e., language developers) and domain expert users (i.e., end-users of the language),...

Electromotive force is defined as the electric potential produced by either an electrochemical cell or by changing the magnetic field. EMF is the commonly used acronym for electromotive force. Q4 What kind of metals exhibit the photoelectric effect?
