To determine which circuit will have the greatest electric current, we need more information about the characteristics of each circuit, such as voltage, resistance, and the arrangement of components (series or parallel).
Generally, Ohm's Law (I = V/R) indicates that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R). Therefore, a circuit with a higher voltage and lower resistance will have a greater electric current.
Please provide the details of each circuit so I can help you determine which one has the greatest electric current.
