37. Three 4 ohm resistors connected in parallel have a potential difference of 16 V applied across them. What is the Total current in the circuit? A. 12A B. 8A C. 10A D. 14A
- A. 12ACorrect
- B. 8A
- C. 10A
- D. 14A
Explanation
Since they are connected in parallel, 1/R=1/4+1/4+1/4=3/4. R=4/3=1.3333 ohm. V=16V. I=V/R=16/1.3333=12A.
