What is a rapid movement of electrical charge from one place to another?
an electrical charge produces a flash of light.
Direct electric current cannot be used to operate A. Electric motors B. Electric heaters C. Electromagnets D. Transformers?
Direct electric current cannot be used to operate D. Transformers.
The ability of a material to transfer heat or electric current is called A insulation C conductivity B porosity D convection?
A. Insulation
What is the material that slows or stops the flow of energy such as heat?
Resistance does not 'slow down' current, it limits the current.The ability of a substance to slow down current is a function of the number of charge carriers per cubic metre of that material.
The current that flows in an electric circuit carries what A chemical energy B mechanical energy C thermal energy D electrical energy?
D. Electrical energy.

What has the author Ira B Current written?

What is open circuit and short circuit?
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.
Direct electric current cannot be used to operate A. Electric motors B. Electric heaters C. Electromagnets D. Transformers?
Direct electric current cannot be used to operate D. Transformers.
When is a motor in star or delta connection?
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.
What will happen if an electric current comes in contact with another electrical current?
They Attract: F = iL x B
What is zeren diode?
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
What are the 3 basic features all electric circuits must have?
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.
Why star connection draw low current?
In star each phase is 120 degree apart in delta angle between phases(R,Y,B) are 60 degree so star connection draw low current.
What is a material that easily allows the flow of electric charge through it is called a semiconductor b insulator c superconductor d conductor?
conducts
The ability of a material to transfer heat or electric current is called A insulation C conductivity B porosity D convection?
A. Insulation
What is the best way to describe induction?
a) The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body. b) The production of an electric current in a conductor by a change of magnetic field.
