Calculate the power dissipated through R4 in units of mW. HINTS: 1. There are multiple ways to compute dissipated power. Carefully choose a sensible form based on what is already known (R). This will dictate what other variable you need to solve for. 2. Series resistors (Same Current, Different Voltage), and Parallel Resistors (Same Voltage, Different Current).
