A combination of three resistors R₁, R2. and R3 in series is connected across a voltage source V7. The voltage drop across R₁ and R3 are 10 V and 36 V, respectively. If the current supplied by the source voltage is 1.4 A and the total power supplied by the source is 70 W, calculate the power dissipated (in watts) by R3.
