Practice Test 7

Considering the information provided, a household device operates from a constant supply voltage $V$ (in V). Resistance $R$ (in $\Omega$) depends on material resistivity $\rho$ (in $\Omega\cdot\text{m}$) and geometry, and Ohm’s Law is $V=IR$. Based on the passage, if voltage doubles and resistance remains constant, what happens to the current?

Considering the information provided, a lightbulb in a household circuit follows Ohm’s Law $V=IR$, where $R$ (in $\Omega$) limits $I$ (in A). Resistivity $\rho$ (in $\Omega\cdot\text{m}$) is a material property affecting $R$. What happens to current if resistance increases and voltage remains constant according to $V=IR$?
