how does electric current flow in the b connection?
do the two bulbs in a series circuit, light when the middle bulb is loose? why?
an electrical charge produces a flash of light.
Direct electric current cannot be used to operate D. Transformers.
The ability of a material to transfer heat or electric current is called conductivity. It measures how easily heat or electricity can move through a material. Insulation, on the other hand, is the resistance to the flow of heat or electricity.
The charged particles that flow when a metal conducts electricity are called electrons. Electrons are negatively charged and move through the metal in response to an electric field, creating an electric current.
That really depends on how the circuit is designed.
Yes, an electric circuit can be completed without connecting it to earth. The circuit needs a complete path for the current to flow back to the source, so as long as the circuit is properly connected and the electrons can flow through the components, it will work without needing an earth connection.

Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
Star (or wye) connection is where each of the three phases has a fourth conductor, neutral, as its current return. Current flow in this configuration is phase to neutral, which is also grounded back at the distribution center. There will be five total connections, phase A, B, and C, neutral, and (protective earth) ground. Delta connection is where each of the three phases uses the prior phase as its current return. Current flow in this configuration is phase to phase, and there is no neutral, though there is still a ground. There will be four total connections, phase A, B, and C, and (protective earth) ground.
Direct electric current cannot be used to operate D. Transformers.
They Attract: F = iL x B
Displacement current can not be measured by ammeter because it is the current which produce between the plate (space)due to change of electric flux and it is directly proportional to the rate of change of electric flux.

A normal diode only allows current to flow in one direction, e.g: A to B. However, current will only flow across this diode A to B when there is a voltage ( called the breakdown voltage), and different normal diodes require different voltages to allow current to flow, e.g: silicon diodes allow current to flow A to B when there is a minimum of 0.6V flowing, at which point the resistance drops, and current flows. A zener diode does exactly this, however, it also allows current to flow in an opposite direction once the breakdown voltage for this direction has been reached. e.g: if a Zener diode has a breakdown voltage of 3.6V, at 3.6V its resistance will drop significantly enough so that current can flow. hopes this helps
3 components ; voltage supply or battery connection wires or wiring a lamp bulb to indicate presence of current flow within the circuit when current is actually flowing within the wires.
Using a metal paper clip to connect the wires at point B completes the electrical circuit. The metal conducts electricity, allowing the current to flow through the bulb. This flow of electricity energizes the filament in the bulb, causing it to light up. Essentially, the paper clip serves as a bridge for electrical flow where the connection was previously open.
