A 6 ohm, 5 ohm, and 8 ohm resistor are connected in parallel with a 30 V battery. What is the total resistance and the current through the 8 ohm resistor?

Answer 1

A) Total Resistance = 19 ohms. Current = 1.58 A

B) Total Resistance = 2.03 ohms. Current = 14.78 A

C) Total Resistance = 2.03 ohms. Current = 3.75 A

D) Total Resistance = 19 ohms. Current = 3.75 A

Answer 2

1/R = 1/6 + 1/5 + 1/8 = 59/120
the current is 30/R = 30 * 59/120 = 59/4 amps

Answer 3

t/6 + t/5 + t/8 = 1

20t + 24t + 15t = 120

current = 30 V / 8 Ω = ? A
