Two electrical circuits have the same 15-volt batteries. Circuit A has 2 ohms of resistance, and circuit B has 6 ohms of resistance. Which of the following statements is correct?
• Circuit B has the same amount of current as circuit A.
• Circuit B has more current than circuit A, as it has less resistance.
• Circuit B has less current than circuit A, as it has more resistance.
• Circuit B has less current than circuit A, as it has less resistance.
My answer is c.
I agree with C. You might watch a veido on it just to make sure you understand it.

To determine which circuit has more or less current, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
For Circuit A:
Voltage (V) = 15 volts
Resistance (R) = 2 ohms
Applying Ohm's Law:
I = V / R
I = 15 V / 2 Ω
I = 7.5 A
For Circuit B:
Voltage (V) = 15 volts
Resistance (R) = 6 ohms
Applying Ohm's Law:
I = V / R
I = 15 V / 6 Ω
I = 2.5 A
Comparing the currents of the two circuits:
Circuit A has a current of 7.5 A, while Circuit B has a current of 2.5 A.
Therefore, the correct statement is:
• Circuit B has less current than circuit A, as it has more resistance.
