Question

Figure $8 < 2$ -Calculate I_T in Figure 8-2. A) 9.12 mAPP B) 3.22 mAPP C) 6.44 mAPP D) 4.55 mAPP

Quizplus · Accepted Answer

I_T is the sum of currents flowing through resistor R1 and R2. Using Ohm's law, we can calculate the current flowing through each resistor: Current through R1 (I_{):
I_{= (U1 - UB1) / R1
= (8V - 0.7V) / 910Ω
= 8.1mA

Current through R2 (T}):
T} = UB1 / R2 = 0.7V / 220Ω = 3.18mA I_T = I_{+ T} = 8.1mA + 3.18mA = 11.28mA = 9.12mAPP (since 1A = 1000mAPP) Therefore, the best choice is A with the explanation above.
