Ejercicio Nº4

Calcular la resistencia total de los siguentes circutos:

RT=  R1 + R2
RT= 300 Ohm + 200 Ohm
RT= 500 Ohm

RT= R1 + R2  + R3
RT = 1000 Ohm + 100 Ohm + 2 Ohm  
RT= 1102 Ohm

RT= 1 / [ 1/R1 + 1/R2 ]
RT= 1/  [ 1/50 Ohm + 1/25 Ohm ]
RT= 1/  [ 0,02  + 0,04 ]
RT= 16,66 Ohm

RT=  1/ [ 1/R1 + 1/ R2 ]
RT=  1/ [ 1/1000 Ohm  +   1/1000 Ohm ]
RT=  1/ [  0,001 +  0,001  ] 
RT= 500 Ohm

RT= 1/ [ 1/RI + 1/R2 + 1/R3]
RT= 1/ [ 1/600 Ohm + 1/200 Ohm + 1/100 Ohm]
RT= 1/ [ 0,0017 Ohm  +  0,005 Ohm + 0,01 Ohm]
RT= 0,0167
