The primary 40-turn coil of an ideal transformer is supplied with 120 V (rms). If the rms voltage output of the secondary coil is 15 V, how many turns are in the secondary coil, and what type of transformer is this? 8 turns, step-down transformer 5 turns, step-down transformer 15 turns, step-down transformer 320 turns, step-up transformer 160 turns, step-up transformer
A cassette recorder uses a plug-in transformer to convert 120 V to 18.0 V, with a maximum current output if 475 mA. A) What is the ratio number of primary turns to the secondary turns?
Part A: A transformer with turns ratio (primary/secondary) of 18:1 is used to step down the voltage from a 120 V wall socket to be used in a battery charger. What is the voltage supplied to the recharger? Part B: The electric motor in a toy train requires a voltage of 9.0 V. Find the ratio of turns on the primary coil to the turns on the secondary coil in a transformer that will step the 120-V household voltage down...
A transformer has 500 turns of wire wrapped around the primary coil and 75 turns of wire wrapped around the secondary coil. If the input voltage on the primary side is 120 V what will be the output voltage of the transformer? 500 V 75 V 18 V 50 V 800 V
The output rms voltage of a 480 W transformer is 240 V and the input rms current is 0.4 A. The primary coil has 200 turns, how many turns does the secondary could have?
Electricity is distributed from electrical substations to neighborhoods at 1.6×104 V . This is a 60Hz oscillating (AC) voltage. Neighborhood transformers, seen on utility poles, step this voltage down to the 120V that is delivered to your house. How many turns does the primary coil on the transformer have if the secondary coil has 120 turns? No energy is lost in an ideal transformer, so the output power Pout from the secondary coil equals the input power Pin to the...
1. A transformer with a primary coil of 1200 turns and a secondary coil of 120 turns has 240 V connected to its primary. What is the output voltage?
An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 6.00 V. The RMS current delivered to the answering machine is 600 mA. If the primary (input) coil of the transformer has 360 turns, then how many turns are there on the secondary (output) coil? Tries 0/20 What is the power drawn from the electric outlet, if the transformer is assumed to be ideal? Tries 0/20 What...
