hoy en este vídeo vamos a encontrar un
ejercicio en el cual es de los
primeritos que se pueden encontrar a la
hora de tener la materia de circuitos
eléctricos entonces vamos a analizar lo
que es este circuito primeramente vamos
a indicar que esto que tenemos aquí es
el voltaje por lo tanto dice que el
voltaje
20 volts ok ya tenemos el voltaje ahora
también tenemos las resistencias estas
resistencias que tenemos aquí son 16 oms
15 oms y 12 oms
entonces las resistencias ya las tenemos
esta es la serie a la resistencia número
1 de la resistencia sería esta número 2
y esta es la resistencia número 3
entonces la cr ya las tenemos pero
tendremos que sumar las están conectadas
en serie cuando están así pegaditas es
porque están en serie está está pegada
si ven muy bien entonces la resistencia
total la vamos a sumar
aritméticamente así como normal y lo que
nos falta encontrar que es ahora si
nuestro ejercicio es encontrar
intensidad de la corriente es así no nos
la dieron en este ejercicio pero la
vamos a calcular entonces vamos
primeramente a sacar la resistencia
total
veamos si nosotros tenemos 16 oms + 15
vamos más 12 oms
tenemos que nosotros sumar la
aritméticamente simplemente una suma así
16 15 y 12 esta suma se haría de esta
forma normal 6 5 11 13
entonces 1-2-3-4 tenemos 43 oms en total
la resistencia total es 43
homs entonces vamos a borrar esta
operación listo ahora para sacar la
corriente vamos a ver lo que es el
triángulo de la ley de ohm para
asegurarnos de hacerlo correctamente
entonces nosotros cuando tenemos este
triángulo lo que vamos hacer es lo
siguiente el voltaje va acá arriba y la
r abajo junto con la y pueden
intercambiarlo estos no importa si los
acomodan al revés pero la que es
importante es la v ahora si esto nos
sirve para nosotros calcular la
corriente si nosotros queremos calcular
corriente que vamos a hacer es tapar u
ocultar la ahí y nos queda b&r como una
división es y es igual al ave sobre r&b
entre r entonces una división vamos a
ponerle aquí si tapamos la y nos queda v
arriba si nos queda la v arriba y la ere
abajo
esto es una división entonces ya
utilizando la ley de ohm que para eso
sirve el triángulo lo que vamos a hacer
en vez de poner br vamos a poner ahora
cuánto vale y cuánto vale r cuánto vale
v dice que v vale 20 entonces ponemos el
20 bolsa sobre r cuánto vale r ya luego
calculamos es 43
homs por lo tanto si nosotros dividimos
20 entre 43 nos va a salir un resultado
de 0.44 amperes que esta es la unidad de
medida de la intensidad de corriente
entonces este sería nuestra respuesta a
este pequeño ejercicio de cómo calcular
resistencia total y la corriente si te
