If we have a parallel plate system with a dielectric liquid in between connected to a voltage source, is it considered an RC circuit? Also, the current at the measuring electrode varies in my simulation of this system, is that normal, if so, why does the current vary with time? Thanks.

Need a circuit drawing for an experiment where I have a DC voltage source connected to an electrode with a parallel electrode being grounded and a dielectric between them. Need to also measure the current running through the circuit to calculate the resistance of the dielectric. I'll be changing the distance between the electrodes as well, not sure if that helps. Thanks.

Suppose that we have a 1000pF parallel-plate capacitor with air dielectric charged to 1000V. The capacitor terminals are open circuited. Find the stored energy. If the plates are moved farther apart so that d is doubled, determine the new voltage on the capacitor and the new stored energy. Where did the extra energy come from?

A parallel plate capacitor with plate separation of 1 millimeter is connected to a battery of 10 volts. If the region between the plates is free space (epsilon_r = 1), calculate the electric field between the plates in Volts/meter, and the electric flux density between the plates in Coulombs/m^2. Suppose a dielectric with dielectric constant epsilon_r = 5 is inserted between the plates. With the battery still connected, calculate the electric field and the electric flux density. Which field has...

Changing Capacitance Yields a Current Each plate of a parallel-plate capacator is a square with side length r, and the plates are separated by a distance d. The capacitor is connected to a source of voltage V. A plastic slab of thickness d and dielectric constant K is inserted slowly between the plates over the time period At until the slab is squarely between the plates. While the slab is being inserted, a current runs through the battery/capacitor circuit. (Figure...

An uncharged parallel-plate capacitor with only air between the plates has C◦ = 0.600 mF. It is connected to an EMF source with E = 6.00 V. a) How much charge Q◦ accumulates on the cap, and how much energy is stored, U◦? b) The capacitor is discharged back to zero, then filled with a dielectric material that brings its capacitance up to C1 = 1.950 mF. What is the value of κ1 for the dielectric material? When connected to...

b) Electrochemistry is the branch of physical chemistry that
studies the relationship between electricity, as a measurable and
quantitative phenomenon, and identifiable chemical change, with
either electricity considered an outcome of a particular chemical
change or vice versa. These reactions involve electric charges
moving between electrodes and an electrolyte (or ionic species in a
solution). Thus electrochemistry deals with the interaction between
electrical energy and chemical change. When a chemical reaction is
caused by an externally supplied current, as in...

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...
