A circuit is constructed with six resistors and two batteries as shown. The battery voltages are V1 = 18 V and V2 = 12 V. The po

The I3 will be 158 A.

<h3>How to find the current through the circuit?</h3>
  • The foundation of circuit analysis is Kirchhoff's circuit laws.
  • We have the fundamental instrument to begin studying circuits with the use of these principles and the equation for each individual component (resistor, capacitor, and inductor).
  • These rules aid in calculating the current flow in various network streams as well as the electrical resistance of a complicated network, or impedance in the case of AC.

To calculate I3 firstly, V4 has to be calculated,

V_{4} =I_{4} R_{4}

V_{4} = V_{2} / R_{4} + R_{5}  * R_{4}

V_{4} = 12 * 135 / 135+61

V_{4} = 8.26V

For I3,

I_{3} = R_{1} /(R1+R3 + (R1+R3)(R2+R6) * (V2 - V1 (R1+R2+R6/R1)

I3=(61)/((61)(50)+(61+50)(141+141)) (12 -18 (1+(141+141)/61)) = -.158 A

Hence, the current through I3 will be 158 A.

Un recipiente contiene 224 dm3 de Ozono de masa 4.561 Kg a 51.09 grados celsius. Calcula la presión del Ozono
kari74 [83]

Answer:

Por lo tanto, la presión del ozono es:

P=0.011\: atm  

Explanation:

Podemos usar la ecuacion de los gases ideales;

PV=nRT (1)

Tenemos:

El volumen V = 224 dm³ = 224 L

La temperatura T = 51.09 C = 324.09 K

La masa es m = 4.561 kg

Lo necesitamos ahora es calvular n que es el numero de moles;

recordemos que el peso molecular del ozono M = 48 g/mol.

n=\frac{m}{M}=\frac{4.561}{48}=0.095\: mol

Finalmente, usando la ecuacion 1 despejamos la presion P

P=\frac{nRT}{V}

P=\frac{0.095*0.082*324.09}{224}  

Por lo tanto, la presion del ozono es:

P=0.011\: atm

Which transition by an electron will release the greatest amount of energy? hurry!
Sphinxa [80]

highest energy level to the ground state.

Explanation:

The transition from the highest energy level to the ground state.

An electron has a discrete amount of energy accrued to it in any energy level it belongs to.

Electrons can transition between one energy level or the other.

  • When electrons change state, they either release or absorb energy.
  • When an atom absorbs energy, they move from their ground to final state which is consistent with the energy of the final state.
  • When electrons release energy, they move from excited state to their ground state.
  • Electrons will release the greatest amount of energy when they move from the highest energy level to the ground state.
