In a balanced wheatstone bridge, if the position of detecor and source are interchanged, the bridge will still remain balanced. This interference can be drawn from

When the power transferred to the load is maximum, the efficiency of power transfer is

Answer - 50 %

When a reisitors R is connected to a current source, it consumes a power of 18w. When the same R is connected to a voltage source having the same magnitude as the current source, the power absorbed by R is 4.5W. The magnitude of current source and the value of R are
