Why does resistance increase in a series circuit?
Depends - in the real world as a resistor gets hotter (current flowing through it) its resistance increases.
What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
Assuming you add more cells in series, the voltage will increase. If you don't change the resistance of the circuit, this in turn will also increase the current.
Are parallel circuits like series circuits?
They are not exactly the same. A series circuit is one complete circuit with not other pathways. A parallel circuit is a complete circuit with multiple pathways . The resistance of a parallel circuit is completely different from the resistance of a series circuit. Therefore, this affects the voltage and the current produced,
Why does the resistance in a series circuit which includes a light bulb increase when the bulb lights up?
When the current increases as a voltage is applied to the bulb it causes the bulb's special wire filament to get so hot that it glows very brightly. The heating causes changes in the normal electron lattice of the filament, creating more barriers to the flow of the electrons and therefore the resistance of the wire increases as it gets hotter.
What would be the effect of adding a load in parallel to a parallel circuit?
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
Why is voltage split over a series circuit?
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
What will cause an increase in current flow in a simple series circuit?
Increase current by either increasing the voltage or decreasing the resistance.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
Why does resistance increase in a series circuit?
Depends - in the real world as a resistor gets hotter (current flowing through it) its resistance increases.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
Total amperage in a series circuit?
Voltage divided by total resistance will give the current. The resistance is simply the sum of all the individual resistances.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
How are resistance combined in a series circuit?
Resistances are additive in a series circuit.
Where is the most resistance lost in a series circuit?
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
