BlackTom AI · Accepted Answer

The given source voltage is vs = -0 Volts, which is mathematically equal to 0 Volts. When a voltage source supplies 0 V, there is no potential difference to drive current through the circuit.

Since R1 and R2 are in series, the total resistance seen by the source is R1 + R2 = 4 Ω + 3 Ω = 7 Ω.

Ohm's law for a single-loop circuit states i = V / R, where V is the source voltage and R is the total resistance in the loop. Substituting V = 0 V and R = 7 Ω yields i = 0 V / 7 Ω = 0 A.

The direction of the current arrow shown is a convention; with zero voltage, the actual current must be zero regardless of the assumed direction.

Potential confusions to watch for: if someone treats -0 V differently from 0 V, they should recall that -0 V is indistinguishable from 0 V in standard arithmetic and circuit analysis; either way, the driving potential is zero.

Therefore, the current i in the circuit is 0 A, expressed to three decimal places as 0.000.
