Three RC circuits have the emf, resistance, and capacitance given in the accompanying table. Initially, the switch on the circuit is open and the capacitor is uncharged. Rank these circuits in order of increasing (a) initial current (immediately after the switch is closed) and (b) time for the capacitor to acquire half its nal charge. Indicate ties where appropriate.
Chapter 16: Temperature and Heat Heat: The energy transferred between objects because of a temperature difference o When the transfer of heat between objects in thermal contact ceases, they are in thermal equilibrium Zeroth law of thermodynamics: if object A is in thermal equilibrium with object B, and object C is also in thermal equilibrium with object B, then objects A and C will be in thermal equilibrium if brought into thermal contact Celsius scale: o Water freezes at 0 o Water boils at 100 Fahrenheit Scale: o Water freezes at 32 o Water boils at 212 Celsius Fahrenheit conversions The Kelvin scale is similar to the Celsius scale, except that the Kelvin scale has its zero at absolute z
