Current is the rate of flow of electric charge in a circuit. It is measured in amperes (A) using an ammeter, which is connected in series with the circuit. The ammeter measures the amount of current passing through a specific point in the circuit.
The maximum current that an electrical appliance can handle is usually indicated on its label or in the user manual. It is important to never exceed this maximum current, as it can cause damage to the appliance and potentially lead to electrical hazards.
The current is what powers an electrical appliance and allows it to function. If the current is too high, it can cause overheating and damage to the appliance. If the current is too low, the appliance may not function properly or at all.
In most cases, the current in an electrical appliance cannot be changed. It is determined by the design and components of the appliance. However, using a voltage regulator or changing the voltage source can indirectly affect the current in an appliance.
AC (alternating current) is the type of current that changes direction periodically, while DC (direct current) flows in only one direction. Most household appliances use AC current, while batteries and electronic devices use DC current.
