Circuit A has a resistance of 7.5 ohms, and circuit B has a resistance of 5 ohms. Which statement about the circuits must be correct? (1 point)
• If the current in circuit A is equal to the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.
• If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.
• If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the current in circuit B.
• If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is equal to the current in circuit B.
• If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.
This statement must be correct because the voltage in a circuit is directly proportional to the current and resistance according to Ohm's Law: V = IR. Since circuit A has a higher resistance than circuit B, in order for the current to be less in circuit A, the voltage must also be less.
