Em um circuito passa uma corrente de 20a pela resistência de 10 ohms qual a corrente que passa numa resistência de 4 ohms

I = current passed in 10 ohm resistor in the circuit = 20 A

R = resistance of the resistor = 10 ohm

E = emf of the battery supplying current in the battery = potential difference across the resistor.

Using ohm's law

E = I R

inserting the values

E = 20 x 10

E = 200 Volts

r = resistance of resistor of value 4 ohm ,  = 4 ohm

i = current passing through resistance "r"

Using ohm's law , current in the resistor is given as

i = E/r

i = 200/4

i = 50 A

the answer is kevlar
