Cual es el diametro de la tierra

Describe the relationship between amperage, voltage, and, as well as resstance.

Nikolay [14]

Answer:

$I=\frac{V}{R}$

Explanation:

Ohms law says that the current in the conductor between the two points is directly related or directly proportional to the voltage by keeping a proportionality of constant which is called resistance.

Mathematically Ohms law can be written as,

$I=\frac{V}{R}$

Here, I is the current measure in ampere or amperage, V is voltage measure in voltage and R is resistance measure in Ohm.

Now the relation between the amperage, voltage and resistance will be,

$I=\frac{V}{R}$

Amperage=Voltage/Resistance

Laurie is moving a dresser with a mass of 250 kg. She does 126 J of work with a force if 14 N. How far does she move the dresser

DanielleElmas [232]

Answer: 9 m

Explanation:

Work is said to be done when an unbalanced force causes displacement of the body.

Force is the product of mass (m) and acceleration (a).

Work = Force × Displacement

⇒W = F.s = ma.s

It is given that mass of the dresser is, m = 250 kg

work done, W = 126 J

Force acting on the dresser, F = 14 N

we need to find displacement, s

⇒126 J = 14 N × s

⇒ s = 126 J/ 14 N = 9 m

Hence, Laurie is able to move the dresser to about 9 m.

Without knowing what kind of data you're trying to show on the graph,
and without knowing what 'kg', 'cm', 'mL', or 's' actually mean, it's really
hard to make any recommendation.

You have a 192 −Ω−Ω resistor, a 0.409 −H−H inductor, a 4.95 −μF−μF capacitor, and a variable-frequency ac source with an amplitu

Elodia [21]

Answer:

Explanation:

Given that,

The resistance of the resistor is

R = 192 Ω

The inductance of the inductor is

L = 0.409 H

The capacitance of the capacitor is

C = 4.95 μF

a. At what frequency is current max?

The current will be maximum at resonance, and resonance frequency is given as

f = 1/2π√L•C

f = 1/2π√(0.409×4.95×10^-6)

f = 111.86Hz

b. Currency at frequency 400rad/s.

w = 400rad/s

So, we need to find the inductive reactance

XL = wL

XL = 400 ×0.409

XL = 163.6 ohms

We also need the capacitive reacttance

XC = 1/wC

XC = 1/400×4.95×10^-6

XC = 505.05 ohms

Then, the impedance of the circuit is given as

Z = √(R²+(XL-XC)²)

Z = √(192²+(505.05—163.6)²)

Z = √(192²+341.9²)

Z = 392.12 ohms

Then, the current that flows can be calculated using

V= IZ

I = V/Z

I = 3.02/392.12

I = 7.7 × 10^-3 A

I = 7.7 mA

Since Xc>XL, then, the source voltage lags the current
