Option A. voltage
How can you increase the current in a circuit?
In a circuit, cutting the resistance by half and leaving the voltage unchanged will double the amperage across the circuit. If the circuit's resistance remains unchanged, the amperage in a circuit can be increased by increasing the voltage
What increases as the current increases?
Ohm's law states that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At constant voltage, current decreases as resistance increases and vice versa.
