Tests are performed on a 50Hz transformer which yield the following results:
Short circuit test: primary voltage = 40V, primary current = 10A, Power input = 20W
Open circuit test: primary = 240V, primary current = 1.2A, Power input = 70W
Determine the equivalent circuit parameters, the turns...
An air-filled parallel-plate capacitor with plate separation d and plate area A is connected to a battery which supplies a voltage Vo between plates. With the battery left connected, the plates are moved apart to a distance of 10d. Determine by what factor each of the following quantities...
