Correct Answer: 6 mA
Correct Answer: 220 Ω
Explanation:
Total Resistance, r = 12 / 13.63
= 0.880 in ohms
Total Resistance, r= 880
Each resistance value = r/4
= 880/4
Each resistance value = 220 ohms.

Correct Answer: the 12 kΩ
Correct Answer: is 9,600 Ω
Correct Answer: 3 W
Correct Answer: increases
Correct Answer: 18 V
