An electric generator contains a coil of 140 turns of wire, each forming a rectangular loop 71.2 cm by 22.6 cm. The coil is plac

Montano1993 [528]

Answer:

11405Volt

Explanation:

To solve this problem it is necessary to use the concept related to induced voltage or electromotive force measured in volts. Through this force it is possible to maintain a potential difference between two points in an open circuit or to produce an electric current in a closed circuit.

The equation that allows the calculation of this voltage is given by,

$\epsilon = BAN \omega$

Where

B = Magnetic field

A= Area

N = Number of loops

$\omega$ = Angular velocity

Our values previously given are:

$N = 140$

$A = 71.2*10^{-2}m*22.6*10^{-2}m=0.1609m^2$

$B = 4.32 T$

$\omega = 1120 rev / min$

We need convert the angular velocity to international system, then

$\omega = 1120 rev/min$

$\omega = 1120rev/min*\frac{2\pi}{1rev}*\frac{1min}{60sec}$

$\omega = 117.2rad/s$

Applying the equation for emf, we replace the values and we will obtain the value.

$\epsilon = BAN \omega$

$\epsilon = (4.32)(0.1609)(140)*117.2$

$\epsilon = 11405Volt$

What was the resistance of the resistor in Part 1? Include your current-voltage plot with the measured slope in your response. E

Karo-lina-s [1.5K]

Answer:

calculate the slope of the line and the slope is equal to the resistance of the circuit m=R

Explanation:

One method for measuring the resistence is to use ohm's law

V = R I

y = mx +b

b=0

m = R

Where we measure various values of voltage and current, with these values we can make a graph of V vs I where we calculate the slope of the line and the slope is equal to the resistance of the circuit
