Question

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

Answer 1

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.
