B_{1}, B_{2}, B_{3}

, and

B_{4}

are identical light bulbs. There are six voltmeters connected to the circuit as shown. All voltmeters are connected so that they display positive voltages. Assume that the voltmeters do not affect the circuit. 85. If

B_{2}

were to burn out, opening the circuit, what would happen to the reading of

V_{1}

? Let

V

be its original reading when all bulbs are functioning and let

\underline{V}

be its reading when

B_{2}

is burnt out. (A)

\underline{V}>2 V

(B)

2 V>\underline{V}>V

(C)

V>\underline{V}>V / 2

(D)

V / 2>\underline{V}
