How would you solve for E(Vin)..in a circuit series with 3resistors values of them.1.2ohm..2ohm..6.8ohm..and the voltage across the 2ohm resistor is 20V...i cant use current!!! to find the voltage across the other resistors abd for Vin..repeat cant use current!!
-
Vin = (V of 1.2 Ohm) + (V of 2.0 Ohm) + (Vof 6.8 Ohm)
Vin = [(1.2/2)*(20V)] + 20V + [(6.8/2)*(20V)] = 100 Volts
Vin = [(1.2/2)*(20V)] + 20V + [(6.8/2)*(20V)] = 100 Volts
-
Ein = 100V
You could find it with proportion rule without using current.But that is a stupid way.
2 : 1.2 = 20 : x
2: 6.8 = 20 : y
Ein = x + y + 20 = 100
