Question

Bruce collects the data on four electric circuits listed in the table. a 3 column table with 4 rows. the first column is labeled circuit with entries w, x, y, z. the second column is labeled voltage in volts with entries 18, 24, 34, 12. the last column is labeled resistance in ohms with entries 38, 34, 70, 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

Answer 1

The Bruce must include X and Z in his report.

We have given  the data on four electric circuits listed in the table

For w :

Voltage, V=18\ V

resistance, $R=38\ \Omega$

What is the formula for ohm's low?

The formula of Ohm's low is V=IR

$I=\dfrac{V}{R}$

$I=\dfrac{18\ V}{38\ \Omega}$

I=0.47

$q=0.47\times8$

So charge,q=It

q=3.76\ C

For x :

Voltage, V=24\ V

$resistance, R=34\ \Omega$

so, V=IR...(Ohm's low)

$I=\dfrac{V}{R}$

$I=\dfrac{24\ V}{34\ \Omega}$

I=0.705

$q=0.705\times8$

So charge,q=It

q=5.64\ C

For y :

Voltage, V=34\ V

resistance, $R=70\ \Omega$

so, V=IR.......(Ohm's low)

$I=\dfrac{V}{R}$

$I=\dfrac{34\ V}{70\ \Omega}$

I=0.485

$q=0.485\times8$

So charge,q=It

q=3.88\ C

For z :

Voltage, V=12\ V

resistance, $R=18\ \Omega$

so, V=IR......(Ohm's low)

$I=\dfrac{V}{R}$

$I=\dfrac{12\ V}{18\ \Omega}$

I=0.66

$q=0.66\times8$

So charge,q=It

q=5.28\ C

Therefore, the circuits X and Z deliver 5.64 C and 5.28 C of charge.

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