So how current stays same while voltage repeatedly fluctuates in AC current?jbriggs444 said:One can plot current versus time, certainly.
For a purely resistive load (an AC power source driving current through a resistor), how does current relate to voltage?
Current does not stay the same in this situation.Benjamin_harsh said:So how current stays same while voltage repeatedly fluctuates in AC current?
AC current, or alternating current, is an electrical current that changes direction periodically. This means that the flow of electrons constantly switches back and forth, instead of moving in one direction like in DC (direct current) currents.
AC current is measured in units of amperes (A). This is done using an ammeter, which is a device that measures the flow of electric current in a circuit.
Current and time are two important factors in AC current. Current refers to the flow of electricity, while time refers to the duration of the current flow. In AC current, the current changes direction over time, resulting in a sinusoidal wave pattern.
The relationship between current and time in AC current is described by the frequency and period of the current. Frequency is the number of cycles per second, while period is the time it takes for one complete cycle. As the frequency increases, the time between cycles decreases.
In DC current, the current remains constant over time, while in AC current, the current changes direction periodically. This means that in DC current, the current and time have a linear relationship, while in AC current, they have a sinusoidal relationship.
