The voltage is a representation of the electric potential energy per unit charge.
The voltage across the circuit is 48 V. Option D shows the voltage across the circuit.
Voltage is defined as the difference in electric potential between two points.
Given that a series circuit contains three 2 Ω resistors and a 6 Ω resistor. The current in each resistor is 4.0 A.
The total resistance across the series circuit is given below.
[tex]R = R_1 + R_2 + R_3 + R_4[/tex]
Where R is total resistance, R1, R2, R3 and R4 are resistors that are connected in series.
[tex]R = 2+ 2+2+6[/tex]
[tex]R = 12 \;\rm ohm[/tex]
The resistors are connected in series hence the current flows across the two points of the circuit are the same which is 4.0 A.
The voltage across the circuit is,
[tex]V = IR[/tex]
[tex]V = 4.0 \times 12[/tex]
[tex]V = 48.0 \;\rm V[/tex]
Hence we can conclude that the voltage across the circuit is 48 V. Option D shows the voltage across the circuit.
