Energy Consumed in a Combined Resistor Circuit

Problem Statement

Consider a circuit with a DC power source (voltage $V$ , negligible internal resistance) connected to three resistors $R_1, R_2, R_3$ . Resistor $R_1$ is connected in series with the power source, while resistors $R_2$ and $R_3$ are connected in parallel with each other after $R_1$ .

Find the Joule heat $Q_3$ generated in resistor $R_3$ during time $t$ after the switch is closed.

Constraints

Source voltage: $V = 48 \text{ V}$
Resistance 1: $R_1 = 4 \Omega$
Resistance 2: $R_2 = 12 \Omega$
Resistance 3: $R_3 = 6 \Omega$
Time: $t = 15 \text{ s}$

Input Format

Find the value of $Q_3$ and give the integer part of the answer (in units of $\text{J}$ ).
