Bruce collects the data on four electric circuits listed in the table.
circuit-voltage-resistance
w-18-38
x-24-34
y-34-70
z-12-18
Bruce must report any circuits that deliver more than 4.0 C of charge in 8.0 s.

Which lists every circuit that Bruce must include in his report?

X and Z
X and Y
W and Y
W and Z

Respuesta :

X AND Z because tats what i got when i answered from edgeunity

Answer : X and Z

Explanation :

For w :

Voltage, [tex]V=18\ V[/tex]

resistance, [tex]R=38\ \Omega[/tex]

so, [tex]V=IR[/tex]

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{18\ V}{38\ \Omega}[/tex]

[tex]I=0.47[/tex]

[tex]q=0.47\times8[/tex]

So charge,[tex]q=It[/tex]

[tex]q=3.76\ C[/tex]

For x :

Voltage, [tex]V=24\ V[/tex]

resistance, [tex]R=34\ \Omega[/tex]

so, [tex]V=IR[/tex]

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{24\ V}{34\ \Omega}[/tex]

[tex]I=0.705[/tex]

[tex]q=0.705\times8[/tex]

So charge,[tex]q=It[/tex]

[tex]q=5.64\ C[/tex]

For y :

Voltage, [tex]V=34\ V[/tex]

resistance, [tex]R=70\ \Omega[/tex]

so, [tex]V=IR[/tex]

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{34\ V}{70\ \Omega}[/tex]

[tex]I=0.485[/tex]

[tex]q=0.485\times8[/tex]

So charge,[tex]q=It[/tex]

[tex]q=3.88\ C[/tex]

For z :

Voltage, [tex]V=12\ V[/tex]

resistance, [tex]R=18\ \Omega[/tex]

so, [tex]V=IR[/tex]

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{12\ V}{18\ \Omega}[/tex]

[tex]I=0.66[/tex]

[tex]q=0.66\times8[/tex]

So charge,[tex]q=It[/tex]

[tex]q=5.28\ C[/tex]

So, the circuits X and Z delivers 5.64 C and 5.28 C of charge.

Hence, Bruce must include X and Z in his report.
