Dear student,

`The center tap is simply another wire which is typically connected somewhere in the middle of the secondary coil.  For example, suppose youhad a transformer with 120VAC primary (2wires) and a 24VAC secondary (2 Wires at each end of the secondary coil).  If you placed a center tap onthe coil, using the center tap and either end you would get 12 VAC if the center tap is truly in the center.  This concept is used inelectronics to generate positive and negative voltages using the center tap as the ground.`

# A cell of emf E and internal resistance r is connected to two external resistance R1 and R2 and a perfect ammeter.The current in the circuit is measured in four different situation: (i)without any external resistance in the circuit (ii)with resistance R1 only (iii)with Ri and R2 in series combination (iv)with R1 and R2 in parallel combination The currents measured in the four cases are 0.42A,1.05A,1.4A and 4.2A,but not necessarily in that order.Identify the currents corresponding to the four cases mentioned above.
