Question

according to ohms law, which combination of units is the same as the unit for voltage?
ohm ÷ ampere
ampere × ohm
ohm + ampere
ampere ÷ ohm

Explanation:

Step1: Recall Ohm's law

Ohm's law is $V = IR$, where $V$ is voltage, $I$ is current, and $R$ is resistance.
The unit of current ($I$) is ampere (A), and the unit of resistance ($R$) is ohm ($\Omega$).

Step2: Determine the unit of voltage

From $V = IR$, substituting the units, we get the unit of voltage $V$ is ampere $\times$ ohm (A$\times\Omega$).

Answer:

ampere $\times$ ohm
