How electric current passes through conductor?
Electric current passes through a conductor when a voltage is applied across it, creating an electric field that pushes charged particles (electrons) through the material. The electrons move in response to this field, flowing from areas of higher voltage to areas of lower voltage. The amount of current that passes through the conductor depends on the material's conductivity and the applied voltage.
What is the force that causes electrons to flow through a conductor known as?
The force that causes electrons to flow through a conductor is known as voltage or electromotive force (EMF). Voltage provides the "push" or potential difference that drives electrons from areas of higher potential to lower potential, resulting in an electric current.
What does voltage cause?
Voltage causes the flow of electric current in a circuit. It is the driving force that pushes electrons through a conductor, allowing electrical devices to operate. The higher the voltage, the more current will flow through the circuit.
What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What makes a current lower and generates more heat?
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?
No. The larger the conductor the lower the resistance and the higher the ampacity.
Can Two or more batteries connected in series generate a higher voltage than one alone?
Yes, two or more batteries connected in series can generate a higher voltage than one alone.

When testing a power transformer with an ohmmeter which winding should have the largest ohmic value?
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
Can rheobase be a threshold stimulus?
Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.
Is gold used in circuit breakers?
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
Do conductors have low resistance?
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.
Why should someone generate power at 220 V?
Only small personal generators generate a voltage of 220 volts. This level of voltage is used usually during power outages. For voltages that power the electrical grid, the voltage is generated at a much higher voltage and then transformed by the use of transformers, into the voltage that is required by different distribution services.
Which combination of metals do you think will give the highest voltage copper and lead or zinc and lead?
The combination of zinc and lead will generate a higher voltage compared to copper and lead. This is because zinc is more electronegative than copper, leading to a greater difference in their electrode potentials and a higher voltage output.

What is a output voltage?
You can compare a power supply to a waterfall of energy. The high of the waterfall is the output voltage, and the quantity of water in the river is the current intensity. The power generate is a combination of the intensity and the voltage: P=UI (the effective power is the result of the multiplication of the voltage and the intensity). That explain why higher the voltage is, less intensity is needed to have the same power. It is the same in a waterfall, higher it is, less water you need to make a mill turning.
