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).
What are Relationship between the voltage drop across the resistors and the currents through the resistors when resistors are connected in parallel?
A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source.
What happen to the voltage across each resistor when all of the resistors are doubled?
Nothing. But the current is halved.
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 is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
When resistors are connected in series in a circuit. what are the relationships between the voltage drops across the resistor and the currents through the resistors?
When resistors are connected in series in a circuit . the voltage drop across each resistor will be equal to its resistance, as V=IR, V is direct proportional to R. An A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source
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.
When resistors are connected in parallel what are the relationships between the voltage drops across the resistor and currents through the resistors?
A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source.
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.
What is the voltage reading of two resistors in series that has a total resistance of 75 K?
The voltage across the ends of the series combination is 75,000 times the current through it.
Resistors of different value in series circuits have different voltages across them The relationship of resistance to voltage is?
A: A series Resistance network may have all kind of different value of resistors but the current will remain the same for each until an addition is made. While the current remains the same for each component the voltage drop across each will be different and all the sum of the voltage drop will equal the voltage source
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.
