A 16.0 Ω, 13.0 Ω, and 7.00 Ω resistor are connected in parallel to an emf source. A current of 6.00 A is in the 13.0 Ω resistor.

Calculate the equivalent resistance of the circuit. Answer in units of Ω.

The current in one parallel resistor doesn't tell us the equivalent resistance of the circuit. And the equivalent resistance of the circuit doesn't depend on the current through any of the resistors, or the voltage applied to them, or even whether there IS any current through any of them.  

Resistors in parallel have the same equivalent resistance even if they're wrapped in tissue, placed in a matchbox, and stored in the back of a drawer in a desk and locked in a dusty warehouse.

The equivalent resistance of 16Ω, 13Ω, and 7Ω all in parallel is the reciprocal of

(1/16) + (1/13) + (1/7) .

That's  1 / (0.0625 + 0.0769 + 0.1429)

That's  1 / (0.2823)

That's   <em>3.543 Ω</em> .

Answer:3.54ohms

Explanation: connection in parallel

1/Rt= 1/R1+1/R2+1/R3

1/Rt= 1/16+1/13+1/7

1/Rt= 91+112+208/1456

1/Rt= 411/1456

411Rt= 1456

Rt= 1456/411

Rt= 3.54ohms

This isn’t homework related but what methods do you guys recommend for shifting realities ? .I’ve tried the raven method for wee
elena55 [62]

Answer:

subs

Explanation:

I've seen subliminals online that are supposed to help shifting. You could see for yourself if they work for you. You could probably also use the method where you act like you already have your desires and results. I have seen a lot of people act as if they have their desires and affirm it constantly. Ex: you want to lose weight, so you act as if you already are your desired weight and tell yourself that you are such and such weight, and don't contradict it by saying that you aren't. I hope that this helps.

Can someone help me?!!!!!
ladessa [460]

Answer:

magnitude: 21.6; direction: 33.7 degrees

Explanation:

When we multiply a vector by a scalar, we have to multiply each component of the vector by the scalar number. In this case, we have

vector: (-3,-2)

Scalar: -6

so the vector multiplied by the scalar will have components

(-3\cdot (-6), -2 \cdot (-6))=(18,12)

The magnitude is given by Pythagorean's theorem:

m=\sqrt{18^2+12^2}=21.6

and the direction is given by the arctan of the ratio between the y-component and the x-component:

\theta = tan^{-1} (\frac{12}{18})=33.7^{\circ}
