How do you find unknown value of a resistor when total resistor values and voltage are known in a series circuit?
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
What else can I help you with?
What does Thevenin's equivalent circuit consists?
The Thevenin's equivalent circuit consist of a voltage source in series with a resistor.
In a series circuit the largest resistance has the largest voltage drop?
In a series circuit, the total voltage supplied by the source is divided among the resistors based on their resistance values. According to Ohm's Law (V = IR), a resistor with a larger resistance will have a larger voltage drop when the same current flows through it. Therefore, the resistor with the highest resistance in a series circuit will indeed experience the largest voltage drop. This is because the voltage drop across each resistor is directly proportional to its resistance.
Is voltage the same across each resistor connected in series?
No, the voltage is not the same across each resistor connected in series. In a series circuit, the total voltage is divided among the resistors based on their individual resistances. According to Ohm's Law, the voltage drop across each resistor is proportional to its resistance, meaning that resistors with different values will have different voltage drops across them. The sum of the individual voltage drops will equal the total voltage supplied by the source.
What are the relations between individual voltages and the total voltages when resistors are connected in series and in parallel?
-- The current in each individual resistor is (voltage across the whole circuit) divided by (the resistance of the individual resistor). -- The current in any individual resistor is less than the total current in the circuit. -- The total current in the circuit is the sum of the currents through each individual resistor.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
In a series circuit why does the largest voltage drop occur across the largest or smallest resistor?
It doesn't. In a series circuit, the largest voltage drop occurs across the largest resistor; the smallest voltage drop occurs across the smallest resistor.
Which resistor of a series circuit receives the larget voltage drop?
The resistor with the most resistance.
When a circuit consists of a capacitor and a resistor in series with a voltage source and the voltage across the resistor becomes zero then the capacitor is?
fully charged.
What is the rule for voltage across each resistor?
The rule for voltage across each resistor in a series circuit is that the total voltage supplied by the source is equal to the sum of the voltage drops across each resistor. In a parallel circuit, the voltage across each resistor is the same and equal to the source voltage.
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
What does Thevenin's equivalent circuit consists?
The Thevenin's equivalent circuit consist of a voltage source in series with a resistor.
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 is the total voltage in a series circuit when multiple resistors are connected in series?
In a series circuit with multiple resistors connected in series, the total voltage is equal to the sum of the individual voltages across each resistor.
The resistor in an R-L series circuit has a voltage drop of 53V and the inductor has a voltage drop of 28V what is the applied voltage of the circuit?
The applied voltage is 53+28 = 81V.
In a series circuit the largest resistance has the largest voltage drop?
In a series circuit, the total voltage supplied by the source is divided among the resistors based on their resistance values. According to Ohm's Law (V = IR), a resistor with a larger resistance will have a larger voltage drop when the same current flows through it. Therefore, the resistor with the highest resistance in a series circuit will indeed experience the largest voltage drop. This is because the voltage drop across each resistor is directly proportional to its resistance.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
