What can electric charges easily flow through?
Electric current is a flow of electric change through a medium can also be carried by ions is an electrolyte by both ions and electrons in a plasma to their Lower Masses electrons in a plasma accelerate more quickly in response.
What metal doesn't change when electricity goes through it?
Electric current is a flow of electric charge through a medium
Why is the gradient on a current-potential difference graph not the resistance?
Resistance is defined by R = V/I where V is potential difference and I is current. It is not: change in pd / change in current - which would be the gradient of the curve. Thus to measure the resistance at a particular pd we simply read off the current at that pd and use the equation above. The problem stems from the way resistors are introduced before non-ohmic components, and for ohmic components it may appear that the gradient is being used for the resistance.
What can change alternating current to direct current?
A diode will let current pass through only in one direction. Note that this will result in a pulsating current; to make the current more regular, you also need capacitors.
How do radiowaves work?
The principle of radio waves is that change of current strength will generate waves. Advantage of this special phenomenon information can be loaded on the waves through modulation.when radio waves arriving receive side through space the change of electromagnetic field generated by waves will lead to current in conductor To extract information from change of current and reach the purpose of messaging.
Do additional resistors affect power?
Of course. Additional resistors change total resistance, which changes current, which affects power.
What causes electrons to move through a wire as a current?
A voltage, which is related to a change in an electric field.
Can I just use resistors to control the current for 3 of the 4 pins in a RGB LED to change its color?
Yes you can reduce the current and therefore the brightness of each colour to change the overall colour. You could even put in three variable resistors with 3 fixed resistors to limit the maximum current. ( when you turn the pots right down to zero).
Electric current in which electrons repeatedly change direction?
AC

What happens to the current when more resistors are added in series?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
Can electrons change energy level?
yes, electrons may change energy levels through a gain or loss of energy.
Why base current is very small?
Small is relative term, current gain of the transistor decides how small base current would be than collector current. Most of the emitter current of electrons diffuses through the thin base into the collector. Moreover, modulating the small base current produces a larger change in collector current.Small is relative term, current gain of the transistor decides how small base current would be than collector current.

How does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
Will the current reaching a lamp after passing through a resistor in series be equalwhy?
A: Because both item are connected is series. Any resistance connected in series will carry the same current no matter of the resistance value or the number of resistors. However for an incandescence lamp the value will change when turn on and change when it is hot, That is because lamps have different property then resistance when cold and hot
Electrical current is the flow of?
Electrons Actually current is counter to the flow of electrons. The definition derives from Benjamin Franklin who knew that something was moving but didn't know if it was positive things or negative things. He had a 50/50 change and guessed the wrong one.
What effect does resister tolerance have on a measured value of circuit current?
A: One example is the gain of an op amp the gain is strictly related to resistors in a closed loop. The gain will change % wise as the resistor change % wise
