2. A 12 V battery produces a current of 6 amps. What is the resistance

Mathematics
1 answer:
Mashutka [201]3 years ago
3 0

Answer:

1) The resistance is 2 ohms.

2) The voltage is 4.95 V.

3) The current is 150 amps.

4) The resistance is 0.05 ohms.

Step-by-step explanation:

Using formula, \text{Resistance}=\frac{\text{Voltage}}{\text{Current}}

1) A 12 V battery produces a current of 6 amps. What is the resistance  ?

Voltage - 12 V and Current - 6 amps

\text{Resistance}=\frac{12}{6}

\text{Resistance}=2

The resistance is 2 ohms.

2) Silver has a resistance of 0.0198 ohms. What voltage would produce a current of 250 amps?

Resistance - 0.0198 ohms and Current - 250 amps

0.0198=\frac{\text{Voltage}}{250}

\text{Voltage}=0.0198\times 250

\text{Voltage}=4.95

The voltage is 4.95 V.

3) What is the current produced by a potential dillerence of 120 volts through a resistance of 0.8 ohms?

Resistance - 0.8 ohms and Voltage - 120 V

0.8=\frac{120}{\text{Current}}

\text{Current}=\frac{120}{0.8}

\text{Current}=150

The current is 150 amps.

4) What resistance would produce a current of 120 amps liom a 6 V battery"?

Voltage - 6 V and Current - 120 amps

\text{Resistance}=\frac{6}{120}

\text{Resistance}=0.05

The resistance is 0.05 ohms.

0.60 gal to 0.12 gal as a fraction
adell [148]

Answer:

0.60 gal to 0.12 gal can be rewritten as:

\frac{0.60}{0.12} =\frac{0.6}{0.6(0.2)} =\frac{1}{0.2}

\frac{1}{0.2}*1=\frac{1}{0.2}*\frac{10}{10} =\frac{10}{2} =5

X + 2 &gt; 7 or 4 - x &gt; 6<br><img src="https://tex.z-dn.net/?f=x%20%2B%202%20%3E%207or4%20-%20x%20%3E%206%20" id="TexFormula1
Doss [256]

So, x > 7 - 2; x >5 or

4 - x > 6; 4 - x - 6 > 0;

4 - 6 -x > 0;

- 2 -x > 0;

-2 > x;

Finally, x > 5 or x < -2;

Please help me with this <br> Thanks
alexira [117]
So you make them the same common denominator
As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40
