What is the most important general difference between a system in steady state and a system in equilibrium?

Short Answer

Expert verified

In steady state the charges inside the conductor are in motion but in equilibrium there are no charges inside the conductor.

Step by step solution

01

Given data

Systems in steady state and equilibrium.

02

Concept of steady state and equilibrium

A conductor with a continuous and steady flow of charges is said to be in a steady state.

A conductor where the charges are stationary and situated at the surface is said to be in equilibrium.

03

Determination of the difference between steady state and equilibrium

The main difference between a conductor in steady state and a conductor in equilibrium is that in steady state the charges inside the conductor are in motion but in equilibrium there are no charges inside the conductor

In a circuit with one battery, connecting wires, and a 12cmlength of Nichrome wire, a compass deflection of 6°is observed. What compass deflection would you expect in a circuit containing two batteries in a series, connecting wires and a36cm length of thicker Nichrome wire (double the cross-sectional area of the thin piece)? Explain.

When a single thick-filament bulb of a particular kind and two batteries are connected in series, 3×1018 electrons pass through the bulb every second. When two batteries in series are connected to a single thin-filament bulb, with a filament made of the same material and length as the thick-filament bulb but a smaller cross-section, only 1.5×1018 electrons pass through the bulb every second. (a) In the circuit shown in Figure 18.109, how many electrons per second flow through the thin-filament bulb? (b) What approximations or simplifying assumptions did you make? (c) Show approximately the surface charge on a diagram of the circuit.

What is the difference between emf and electric potential difference?

How can there be a nonzero electric field inside a wire in a circuit? Isn’t the electric field inside a metal always zero?

Suppose that a wire leads into another, thinner wire of the same material that has only a third the cross-sectional area. In the steady state, the number of electrons per second flowing through the thick wire must be equal to the number of electrons per second flowing through the thin wire. If the drift speedV1¯in the thick wire is 4×10-5ms, what is the drift speed V¯2in the thinner wire?
