This is equal to one coulomb of charge in one second.
Current is the measure of how much electric charge flows through a complete circuit. The more charge there is, the bigger the current. Generally, larger electrical items need a higher voltage and current than smaller electrical items.
Electric current is when electric charges flow from one place to another in a circuit. This current often travels through conductors or wires. A circuit is a closed path in...
