Question:

Calculate the general current flowing through a closed loop circuit with a source voltage of 20V and two parallel 5ohm resistors.

Inactive
Uche O.

Using ohm's law (V= IR) where V = voltage, I = current and R = total resistance. in this case since the Resistances in the circuit are in parallel the total resistance = ((5x5)/(5+5)) = 2.5 ohms Therefore current(I) through the circuit = 20/2.5 = 8Amps
