What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Can we use transformer as a generator?
No. Transformer essentially can step up or step down voltage or provide same voltage across the secondary side. It can not generate voltage on its own. Generator is essentially a rotating device. Transformer is a static device.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
Why keep a voltage transformer secondary open?
it is keep open so as to supply voltage to the loadAnswerThe secondary winding of a transformer is NOT necessarily kept open, unless you want to disconnect its load.
What class is a transformer that converts 110 volts to 24 volts?
A transformer that reduces voltage is classed as a step down transformer.
Why do we need a transformer if we use a welding machine?
A welder requires high current at the expense of voltage, The transformer reduces the voltage allowing a higher current to operate the welsing machine.
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
What is the Name of the transformer in which the output AC voltage is less than the input AC voltage?
It is a step-down transformer.
How does a stabilizer?
A home voltage stabilizer reduces (buck) or increases (boost) the out put voltage for respective increase and decrease in line voltage. To reduce output voltage the relay cutoff some transformer winding turns, and to increase output voltage the relay add some transformer winding turns in predefined steps.
Name the type of voltage that can be changed by transformer?
AC
How does a stabilizer works?

To reduce output voltage the relay cutoff some transformer winding turns, and to increase output voltage the relay add some transformer winding turns in predefined steps.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What happens to the current as the voltage is increased by the step up transformer?
Compare a transformer to a balancing act. Both side need to remain equal.The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.The current of a step up transformer will be higher on the primary side that that of the secondary.Apply voltage and current to this concept and you will see that the transformer will remain balanced.The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.
What is the name of the device that changes the ratio of a current in voltage?
A transformer. it steps up / down voltage, and steps down / up current.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
