Problem

Three identical batteries are each connected to their own RC charging circuit as described below. 1)

R=1.0\,\text{k}\Omega

C=1.0\,\mu\text{F}

R=2.0\,\text{k}\Omega

C=0.50\,\mu\text{F}

R=0.50\,\text{k}\Omega

C=4.0\,\mu\text{F}

Rank the magnitude of the current in the resistor of each circuit at the instant

t=\tau

(one time constant for that circuit) from greatest to least. Express your answer in the form “__ > __ > __.”
