How much current will flow through the resistor R2 if R1=R2=10 ohms and R3=20 Ohms?
The circuit in the given figure is a series circuit. We know that the same current flows through all the resistors connected in series. The equivalent resistance of the given circuit = R1+R2+R3 = 10+10+20 = 40 ohms. $8072_w139_h14.png$
