The power drawn from the DC power supply can be calculated using the formula P = V * I, where V is the voltage (VCC = 10 V) and I is the total current drawn from the power supply. The total current is the sum of I1 and ICQ, which is 450 μA + 10.55 mA = 11 mA (since 1 mA = 1000 μA). Therefore, P = 10 V * 11 mA = 110 mW.
