Answer:
Explanation:
Use the parallel resistance formula to find the total circuit resistance (R).
R = 1/(1/r1 +1/r2 +1/r3 +1/r4)
R = 1/(1/10 +1/30 +1/25 +1/15) = 1/(15/150 +5/150 +6/150 +10/150)
R = 150/(15 +5 +6 +10) = 150/36 = 25/6 = 4 1/6 . . . Ω
The total resistance is 4 1/6 Ω.
__
The circuit voltage is the product of current and resistance:
V = IR = (2)(4 1/6) = 8 1/3 . . . volts
The circuit voltage is 8 1/3 volts.
