If you make a mistake in polarity when measuring the value of DC voltage in a circuit with a digital VOM, what will happen?

Answer:

Changes the sign of the measured electrical potential

Explanation:

If you have a positive test charge q_o with an electric field, and it moves from point A to point B, keeping the balance without exception, then the work that the agent that carries the load has to do is equal to:

V_B-V_A=V_B_A=\frac{W_A_B}{q_o}

Which is called electric potential difference.

This work can be a negative, positive or null value, and the electric potential corresponding to B is less, greater or equal respectively to the potential of A.

On a VOM digital multimeter the black color is always connected inside the pin or connector marked COM, short for COMMON (Common/Ground/0 V) and the red tip is connected inside the V pin (Highest electrical potential )

Let:

V_B=Highest\hspace{3} electrical\hspace{3} potential\\V_A=Lowest\hspace{3} electrical\hspace{3} potential

Also, let's assume:

V_B=12V\\V_A=1

So, if you meaure the voltage with the correct polarity, the VOM will show you this result:

V_B-V_A=V_B_A=12-1=11V

On the other hand if you make a mistake in polarity, the VOM will show you the same result but with a different sign:

V_A-V_B=V_A_B=1-12=-11V

 Nothing happens. Just reverse the probes of multimeter & measure it again, this time around it should come positive

The company A produces products a, and the company B produces products b. It is known that 3 percent of companies that produce p
slava [35]

Answer:

probability = 0.183 %

Explanation:

given data

produce products = 3 %

probability for producing products b = 6.1

solution

Both companies produce different products and the likelihood of bankruptcy varies depending on the product produced. So, the bankruptcy potential of A and B companies is independent.

we will  multiply the probability of each company's bankruptcy and that will be

probability = P(A=bankrupt) ×  P(B=bankrupt)

probability = 3% × 6.1%

probability = 0.183 %

If 4x = 32, find the value of 35 - 5x<br> 0-5<br> 03<br> 0-3<br> O 5
vlada-n [284]
4x=32
You would divide 32/4 to find x which is 8. So since we found x we will apply it to the equation
35 - 5(8) = 35-40 = -5
