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

A5 A

B2.5 A

C20 A

D10 A

Answer:

B. 2.5 A

Read Explanation:

  • 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
