What do we call the voltage that is provided by a transformer?
This is the transformed voltage, but it might also be identified as the secondary voltage as it is taken from the secondary winding.
What is a maximum voltage across a resistor?
The voltage across the resistor is whatever voltage is applied. The only maximum here would be a voltage that would damage the resistor. If you think this might happen, you'll have to look up such a voltage from the data sheets.
Can you use a higher voltage rating capacitor with the same uf rating?
Yes, it will work fine. The downside is that it might cost more than one of the lower voltage rating, or that it might be physically larger. A capacitor voltage rating is a maximum, so any lower voltage is also acceptable.
What is the use of single phase variac in circuits?
A variac a variable auto-transformer, allowing the output voltage to be adjusted from zero up to a maximum voltage, which might be 20% greater than the supply voltage.
Will secondary health insurance cover what primary does not?
Not necessarily; a secondary insurance policy or plan might only provide additional benefits up to the maximum that it will pay for a specified service. If both plans have rates that are similar, this might result in a small additional payment. Some secondary insurance or health plans might pay up to their maximum -- in addition to what the primary pays, which would result in a higher payment against a claim.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
Why voltage regulation is necessasory?
Voltage may fluctuate due to improper wiring/groundings or sometimes due to sudden load changes. So as to give constant output voltage we need voltage regulation. If we let the voltage to fluctuate then it might cause damage to the equipments
In a pentode power amplifier the effective impedance of the load is 600 ohms The signal current varies between 50 and 200 ma The effective voltage across the secondary of the transformer is 10.6 volts?
It might be. Or it might not. You need to specify the transformer's turns ratio or its impedance ratio, and th eload on the secondary.
What is impedance voltage in a transformer?
Power transformers have an impedance (Z) rating that is listed in %. So the nameplate might state 5% Z for example. What this means is that when the secondary conductors are bolted together then 5% of the rated primary voltage is applied and will generate 100% current in flow in the secondary. Example: you have a 75KVA Delta-Wye 5% Z transformer with a 480V primary rating and 208/12 secondary rating. The amp rating of the secondary is 208A [75,000/(1.732x208)] So if you applied 24VAC to the primary with the secondary bolted together with busbar then you would have 208A of current flow.
Can you use a 6 volt adapter on 9 volt equipment?
No, the unit might work but the low voltage will cause unit to stop.
