Question
ex 7.
which law states that the sum of currents entering a junction equals the sum leaving it?
image of a circuit with a battery, three resistors in parallel, current labels ( i_t ), ( i_1 ), ( i_2 ), ( i_3 ), and the equation ( i_t = i_1 + i_2 + i_3 )
\\( \bigcirc \\) ohm’s law
\\( \bigcirc \\) kirchhoff’s current law
\\( \bigcirc \\) faraday’s law
\\( \bigcirc \\) kirchhoff’s voltage law
Brief Explanations
- Ley de Ohm: Relaciona voltaje, corriente y resistencia ($V = IR$), no sobre junciones de corriente.
- Ley de Corriente de Kirchhoff (KCL): Establece que la suma de corrientes entrantes en una unión es igual a la suma de corrientes salientes (lo que coincide con la descripción del problema y la fórmula $I_T = I_1 + I_2 + I_3$).
- Ley de Faraday: Se refiere a inducción electromagnética, no a corrientes en junciones.
- Ley de Voltaje de Kirchhoff (KVL): Se refiere a la suma de voltajes en un lazo cerrado, no a corrientes en junciones.
