Question
if the wires in this circuit were thinner, would they have lower resistance? they would be the same. no yes
Brief Explanations
Resistance formula \(R =
ho\frac{l}{A}\) (\(
ho\) is resistivity, \(l\) is length, \(A\) is cross - sectional area). Thinner wires have smaller \(A\). When \(A\) decreases (assuming \(
ho\) and \(l\) are constant), \(R\) increases. So thinner wires do not have lower resistance.
