- 0.2 A
- 180 A
- 0.1 A
- 0.5 A
Show answer and solution
Correct answer: A. 0.2 A
We have I = V/R.
That is I = 6/30.
So I = 0.2 A.

Three resistors of 5 Ω each are connected in parallel. Find R_total.
- 15 Ω
- 5/3 Ω
- 1.5 Ω
- 5 Ω
Show answer and solution
Correct answer: B. 5/3 Ω
1/R = 3 × 1/5 = 3/5, so R = 5/3 Ω ≈ 1.67 Ω.
