What happen to voltage and current when rheostat is adjusted from maximum to minimum resistance using both ammeter and voltmeter?
When a rheostat is adjusted from maximum to minimum resistance, the overall resistance in the circuit decreases. As a result, the current flowing through the circuit increases, which can be observed on the ammeter as a higher reading. Conversely, the voltage across the rheostat will decrease, as the voltage drop across a lower resistance is less, which can be monitored using the voltmeter.
Will voltage or current be higher in a circuit during short circuit?
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
Will the voltage in this circuit be greater in A or B?
To determine if the voltage in circuit A or B is greater, we need to consider the components and configuration of each circuit. If circuit A has a higher voltage source or lower resistance compared to circuit B, then A will have a greater voltage. Conversely, if circuit B has a higher voltage source or lower resistance, it will have the greater voltage. Without specific details about the circuits, it's impossible to definitively answer the question.
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit
What benefit is there for getting higher open circuit voltage?
There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
How can you make the resistance higher in a circuit?
A: practically any series resistance will do that
The number of ohms in a circuit is a measure of the?
resistance to the flow of electrical current in the circuit. It is a measure of how much opposition the circuit presents to the flow of electricity. The higher the number of ohms, the greater the resistance in the circuit.
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
What is the roll of bleeder resistance in LC filter circuit and what will happen if the bleeder resistor is not used in circuit?

What happens to amps when you increase the resistance of a circuit?
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
What causes an increase of resistance in a series circuit?
An increase in resistance in a series circuit can be caused by adding resistors in series, increasing the length or cross-sectional area of the wire, or using a material with higher resistivity. This leads to a higher total resistance in the circuit, which can reduce the current flowing through it.
The value of resistance of an short circuit?
The value of resistance when there is a short circuit varies depending on the nature of the fault, but it could be fractionally above zero or higher.
What determines the current ine each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
