Voltage and current question

[linda123]

The voltage is between one phase and neutral. Does it mean that the current flows from the phase line to neutral?

What do voltage and current mean in terms of fundamental definitions?

Household wiring uses alternating current. For half of the cycle, the voltage is higher on the hot line than on neutral, and thus current flows from hot to neutral. For the other half of the cycle, the voltage is lower on the hot line than on neutral, and thus current flows from neutral to hot.

Voltage is analogous to water pressure; current is analogous to the fluid flow caused by a difference in pressure.

Voltage and current are fundamental concepts in electricity and are related to each other through Ohm's Law. Voltage is a measure of the potential difference between two points in an electrical circuit, while current is the flow of electric charge through a conductor.

In terms of the given question, the voltage being between one phase and neutral means that there is a potential difference between these two points. This can be visualized as a "push" or force that drives the flow of electrons. However, the direction of current flow is not determined by the voltage alone. It is also dependent on the resistance of the conductor and the direction of the electric field.

In most cases, current will flow from a higher voltage point to a lower voltage point. So, in this scenario, if the neutral line has a lower voltage compared to the phase line, then the current will flow from the phase line to the neutral line. However, if the neutral line has a higher voltage, then the current would flow in the opposite direction.

Overall, voltage and current are interrelated and cannot be fully understood without considering other factors such as resistance and electric field direction.
