1. An ideal transformer with a 450 turn
primary connected to a 600 V, 60 Hz supply
line needs to output 240 V from the
secondary. A 100 load is connected
across the secondary. How many turns the
secondary must have to output the desired
voltage? What is the current through the
load? What is the current drawn through
the primary?
An ideal transformer having 50 turns on the primary and 1250 turns on the secondary is connected to a 100 V, 60 Hz source. The load across the secondary an RL-load with R = 250Ω and L = 0.5 H.
i. What is the peak value of the flux in the core of the transformer?
ii. What is the secondary voltage?
iii. What is the primary current
In the circuit in Figure 2, the capacitor connected to the a-b terminals of the transformer anda circuit consisting of resistance is defined as a load circuit.
