What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
Current ratio is opposite than voltage ratio in transformer?
Yes
How do you calculate primary current?
If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
What is current ratio on a transformer?
It's approximately the inverse of the voltage- or turns-ratio:
How do you change the ratio of a current to voltage?
Change the resistance in the circuit
What does 74 stand for in IC?
it defines the voltage and current ratio.
Device than changes the ratio of current to voltage?
A transformer. it steps up / down voltage, and steps down / up current.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
What is the realtionship among voltage current and resistance in a circuit?
Ohm's Law Voltage = Current x Resistance
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
