One coulomb per second is defined as which electrical unit?

Explanation:
Electric current is the rate at which charge flows past a point. The unit for that rate is the ampere, defined as one coulomb of charge passing per second. So when charge moves at 1 C every second, the current is 1 ampere. The other units describe different things: voltage is the potential difference pushing charges, resistance is how much a material resists that flow, and power is the rate of energy transfer, equal to voltage times current (a volt-ampere relationship for practical terms).
