Question

according to ohm’s law, which combination of units is the same as the unit for resistance?
○ volt ÷ ampere
○ ampere × volt
○ volt + ampere
○ ampere ÷ volt

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is given by \( V = IR \), where \( V \) is voltage (in volts), \( I \) is current (in amperes), and \( R \) is resistance (in ohms).

Step2: Rearrange for Resistance

Rearranging the formula to solve for resistance, we get \( R=\frac{V}{I} \).

Step3: Determine Units for Resistance

The unit of voltage \( V \) is volt, and the unit of current \( I \) is ampere. From \( R = \frac{V}{I} \), the unit of resistance is volt divided by ampere (volt \( \div \) ampere).

Answer:

volt \( \div \) ampere
