transformer has an input of 76 V and an Output of 33 V. If the input is changed to 71 V what the output would be? Calculate to one decimal

A transformer has an input of 96 V and an output of 22 V. If the input is changed to 78 V. what the output would be? Calculate to one decimal

A series DC motor has a resistance of 7 Q between its terminals. The motor runs at 1,259 rpm at 230 V taking a current of 12 A. What will be the speed at which the motor runs when it is connected in series with a 4 Q resistance, if there is no change in the supply voltage and current. Give your answer to two decimal places. ****** S Next > apba < Previous 1391

Draw a schematic circuit diagram showing a DC power source and two light bulbs connected in series, which in turn are connected to two light bulbs and a  motor, all connected in parallel with each other. The complete circuit is controlled by one switch and protected by a fuse. An ammeter is connected to measure the current through the motor and a voltmeter measures the voltage of the DC power source.

A certain transformer has 120 V across the 100-turn primary coil and has 5 turns in the secondary coil. If the current in the primary coil is 0.1 A, how much power is dissipated in the secondary coil?

A student in the laboratory connects a 20 Ω resistor, a 22 Ω resistor, and a 39 Ω resistor in series and then connects the arrangement to a 48-V dc source.

R1 is the resistance of the primary winding of a transformer. The turns ratio in terms of primary to secondary is a. What is the equivalent resistance of the primary referred to from the secondary?
