How do you randomly choose resistors for your voltage divider circuit?
you don't. you calculate resistors required for your needs then select closest available resistors made with acceptable tolerance.
In a circuit the voltage across all resistores is the same?
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
What happens to the voltage values of other resistors when a short occurs in one of them?
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
Does the resistors current changes if the voltage across a fixed resistors is cut in half?
If the voltage across a resistor or resistors is halved, then the resulting current will also fall by half.
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
Did the the total voltage across the resistors does not depend on the resistor value?
It depends on where and how the resistor is placed in a circuit. A string of series resistors will split the voltage across all them depending on their values. All of the resistors in parallel will have the same voltage across all of them no matter what their resistance is.
What are photo resistors?
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
Will the resistors ohmic value increase if you increase the voltage?
No.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
Advantage of using connecting resistors series in terms of current and voltage?
if resistors connected in series the resistance will increase.Then it limit the flow of current through it. voltage may be increased. A: by connecting any resistors in series it will limit the current flow it will effect the current but never the voltage applied
If two resistors have same voltage drop in a series circuit it means?
It means the two resistors have same resistance
