Q1
Considering the information provided, a lightbulb in a household circuit obeys $V=IR$; resistance $R$ (Ω) controls current, and resistivity $\rho$ (in $\Omega\cdot\text{m}$) is intrinsic to the filament material. What happens to current if resistance increases and voltage remains constant according to Ohm’s Law ($V=IR$)?
