A fixed resistor is cannected in parallel with a variable resistor, both are connected to a real battery (internal resistance is not negligible). Originally the fixed and variable resistors have the same resistance As the resistance of the variable resistor is decreased, the current through the fixed resistor

The circuit shown has resistor of equal resistance R. Find the equivalent resistance between A and B, when the key is closed.

The circuit shown has resistor of equal resistance R. Find the equivalent resistance between A and B, when the key is closed.

The effective resistance of two resistors in parallel is (12)/(7) Omega . If one of the resistors is disconnected the resistance becomes 4 Omega . The resistance of the other resistor is
