Can a vector have a component greater than its magnitude in higher level physics?
yeah, it can. for example consider two antiparallel vectors of magnitude 5,3 whose resultant is 2, which is smaller than both components.....
How is a fraction related to its reduce form?
The two are equivalent.The two are equivalent.The two are equivalent.The two are equivalent.
Two ratios that are equivalent are said to be in what?
Two ratios that are equivalent are said to be in proportion
What are two decimals that are equivalent to 0.700?
two decimals that are equivalent to 0.700 = 0.7, 0.70
Which two decimals are equivalent to 7.5?
two decimals are equivalent to 7.5 = 7.50; 7.500
Where does a SCR differ from a power transistor in operation?
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
State two advantages of a triac as compared to an SCR?
triac act as a ac contactor
What is an antiparallel?
An antiparallel is a line which forms equal angles with two other lines but in opposite directions.
What is a gateless triac?
A gateless triac is a diac. It is often used in the gate circuit of a triac to balance out the firing voltage for the triac in both quadrants, so that there is no DC offset in the controlled load. This is because, while the gate trigger voltage is often asymmetric in the two quadrants, the M1/M2 breakdown voltage is often symmetric.
What does antiparallel mean?
Antiparallel refers to a configuration where two molecules or structures run in opposite directions. In terms of DNA, antiparallel describes the orientation of the two strands running in opposite 5' to 3' directions. This allows for complementary base pairing to occur between the strands.
Are Single stranded DNA molecules are said to be antiparallel when they lined up next to each other but oriented in opposite directions?
No, single stranded DNA molecules aren't considered antiparallel. Antiparallel refers to the orientation of the two strands in a double-stranded DNA molecule, where one runs 5' to 3' and the other runs 3' to 5'. Single-stranded DNA is usually unidirectional and doesn't have a complementary strand to be antiparallel to.
Is DNA antiparallel?
Yes, DNA is antiparallel. This means that the two strands of the DNA double helix run in opposite directions, with one strand running 5' to 3' and the other running 3' to 5'. This antiparallel arrangement allows for complementary base pairing between the strands.
What is an antiparallel force?
Antiparallel forces are forces that act in opposite directions along the same line of action. This means that the forces are equal in magnitude but opposite in direction. In a free-body diagram, antiparallel forces are typically represented using arrows pointing in opposite directions along a straight line.
Contrast the scr and the triac?
Essentially an Scr is a solid state switch that will only allow current to flow in one direction. A triac is essentially two scr's in Anti- parallel that allows current to pass in both directions.
Can you use Diac and Triac for dc supply?
The diac conducts in both directions at approximately the same voltage, making it unsuitable in an AC to DC supply. The triac also conducts in both directions, based on a gate voltage which is slightly different in the two usable quadrants. That is why the diac is often used to trigger the triac - it makes the two conduction cycles more symmetric. In both cases, the diac/triac does not make sense for an AC to DC supply, but it works well in an AC voltage regulator, such as a lamp dimmer or motor speed controller.
Why we don't use triac in case of ac controlled rectfier rather than scr?
A TRIAC does not have a symmetrical turn-on point in the opposite quadrant. This will introduce a DC bias, which you probably don't want. You can use an SCR, and then add diodes to allow it to operate in the opposite quadrant, or you can use two SCR's. Alternatively, you can use a DIAC in the TRIAC's gate circuit to balance the turn on point.
Are DNA strands oriented antiparallel to each other?
Yes, DNA strands are oriented antiparallel to each other, meaning one strand runs in the 3' to 5' direction while the other runs in the 5' to 3' direction. This is important for the complementary base pairing that occurs between the two strands.
