1. The problem statement, all variables and given/known data
The inductance is 0 in the RLC Circuit. the rms voltage across the genreator and the resistor are 45, and 24V. Wats the voltage across the capacitor? 2. Relevant equations Vrms= Vmax/ Sq rt 2 V c = IX c , 3. The attempt at a solution V= I/R I= V/R 24/45= 8/15A C can be calculated since theres no F or L

Recall the Kirchoff's voltage law. The voltage across all elements in a loop added is zero. Here there are only three elements ( generator, resistor and capacitor). The sum of voltages across them should be zero. You know voltage across two elements. Hence it is easily to calculate the voltage across C directly.
