Question

Two resistors of 4Ω each are connected in parallels to a 5 V battery source. The total current in the circuit is?

• A. 5 A
• B. 2.5 A
• C. 20 A
• D. 10 A

Answer 1

Answer:

B. 2.5 A

• Equivalent resistance (R) of two 4Ω resistors in parallel is given by:

• 1/R = 1/4 + 1/4 =2/4 = 1/2 R =2Ω

• Using Ohm's law, current (I) =V/R = 5V / 2Ω = 2.5 A
