Polaczono szeregowo cewke ul=120 rezystor ur=100 i kondensator uc=50 Napiecie miezone voltomierzem nie moze byc: u>100 u<1

romanna [79]

Answer:

Translated from Polish language:

Coil connected in series ul = 120 resistor ur = 100 and capacitor uc = 50 Voltage with voltmeter must not be:

The voltmeter must not be connected in series rather it should be connected in parallel to the circuit to provide much effective results for analyzing the circuits potential difference.

Using the definition of moment of inertia, calculate icm, the moment of inertia about the center of mass, for this object.

Step2247 [10]

The masses have no inertia about their own CM, and "the object" is the two masses. 
1. Icm (at point A) = 2mr^2

An 1,840 W toaster, a 1,460 W electric frying pan, and a 50 W lamp are plugged into the same outlet in a 15 A, 120 V circuit. (T

shutvik [7]

Answer:

Explanation:

Given

Power drawn by toaster $P_1=1840\ W$

Power drawn by Electric fan $P_2=1460\ W$

Power drawn by lamp $P_3=50\ W$

Voltage applied $V=120\ V$

If appliances are applied in parallel then Voltage applied is same

Power is given by $P=\frac{V^2}{R}$

Resistance of toaster $R_1=\frac{120^2}{1840}=7.82\ \Omega$

Resistance of electric Fan $R_2=\frac{120^2}{1460}=9.86\ \Omega$

Resistance of toaster $R_3=\frac{120^2}{50}=288\ \Omega$

Current is given by

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

$I_1=\frac{120}{7.82}=15.34\ A$

$I_2=\frac{120}{9.86}=12.17\ A$

$I_3=\frac{120}{288}=0.416\ A$
