Question

if a 12v circuit was drawing .6 amps of current, what is the resistance? 5 points your answer if a 18v circuit was drawing 2 amps of current, what is the resistance? 5 points your answer if a 120v circuit has the resistance of 6 ohms, what is the current? * 5 points your answer

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $V = IR$, where $V$ is voltage, $I$ is current, and $R$ is resistance. We can rearrange it to solve for the unknowns. For the first two questions we solve for $R$ ($R=\frac{V}{I}$), and for the third we solve for $I$ ($I = \frac{V}{R}$).

Step2: Solve the first problem

Given $V = 12$ volts and $I=0.6$ amps. Using $R=\frac{V}{I}$, we have $R=\frac{12}{0.6}=20$ ohms.

Step3: Solve the second problem

Given $V = 18$ volts and $I = 2$ amps. Using $R=\frac{V}{I}$, we get $R=\frac{18}{2}=9$ ohms.

Step4: Solve the third problem

Given $V = 120$ volts and $R = 6$ ohms. Using $I=\frac{V}{R}$, we obtain $I=\frac{120}{6}=20$ amps.

Answer:

20 ohms
9 ohms
20 amps
