following transformer circuit VSource=12.0volts, RSource=4, the number of turn on the left-handside is 100 and on the right-handside is 800. RLis 700. a.Find the voltage across RL

A transformer has 472 turns on its primary and 108 turns on its secondary. (a) Is this a step-up or a step-down transformer?   (b) If a voltage of 103 V is applied to the primary and a current of 0.4 A flows in these windings, what are the voltage output of the secondary and the current in the secondary?voltage  Vcurrent  A

What relationship exists between a coil's inductance value and the amount of emf or voltage it produces.

Please answer and box.

A circuit consists of 18 volts battery, a 72 mH inductor and two 50 ohms resistors connected in parallel. a) Find the characteristic time constant for the circuit. b) What is the current in the circuit at two characteristic time intervals after the switch is closed? c) A long-time-interval after the switch is closed L R R ww

A series RL circuit with R = 19 0, and L = 6 H has a constant voltage E = 150 V applied att = 0 by the closing of a switch. R E t =0 Find the time at which VR = VL. elle
