What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
What will happen to a bulb when you move it closer to the battery on a circuit?
Nothing special should happen. What matters for the bulb is the voltage difference between its ends.
What would happen to the voltage and the magnet is withdrawn from the coil?
the voltage increases
What will happen to the circuit if the bulb if removed from its holder?
Nothing will happen to circuit..... as usual the circuit would be supplying 220v(if india) and certain current...but there is no bulb to consume power...
What might happen to the bulb if you added too many extra batteries to the circuit?
If you added the batteries in parallel, then the bulb would stay on for a long time and nobody would get any sleep. If you added the batteries in series, then the voltage across the bulb would eventually become excessive and the bulb would burn out.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
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 happen if you apply triangular input to transformer?
there will be no neutral point in the circuit and high voltage will be across the transformer coils
What two things happen when the number of appliances connected to the multiple socket is increased?
The amperage of the circuit increases and the voltage drop across the appliances will tend to increase.
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 will happen to the total current if you keep adding bulbs in parallel to the circuit?
Adding more lamps in parallel (across) a line will cause total current to climb. It will keep climbing (increasing) until a load protection device (circuit breaker or fuse) breaks the circuit or until something fails because of excessive current.
What happen to the voltage when the collector current increases in a biased circuit?
it dies
What will happen if a piece of string is being used to complete a close circuit?
The piece of string will act as an insulator. Insulators will not carry circuit current when a voltage source is applied across it. Therefore nothing will happen if a piece of string is used to complete an electrical circuit.
What is a maximum voltage across a resistor?
The voltage across the resistor is whatever voltage is applied. The only maximum here would be a voltage that would damage the resistor. If you think this might happen, you'll have to look up such a voltage from the data sheets.
What happen to the current values when one of the voltage sources is disconnected from the circuit?
Without the actual circuit diagram (schematic), this question cannot be answered.
What happens in series resonance?
The properties of a series alternating-current L-R-C circuit at resonance are:the only opposition to current flow is resistance of the circuitthe current flowing through the circuit is maximumthe voltage across the resistive component of the circuit is equal to the supply voltagethe individual voltages across the inductive and capacitive components of the circuit are equal, but act in the opposite sense to each otherthe voltage appearing across both the inductive and capacitive components of the circuit is zeroif the resistance is low, then the individual voltages appearing across the inductive and capacitive components of the circuit may be significantly higher than the supply voltage
When do you get a short curcuit?
A short circuit occurs when electricity can pass with little resistance between two parts of a circuit where it is not intended to. Typically, it will happen when two uninsulated wires touch accidentally, or a conducting (metal) part contacts two uninsulated parts of the circuit. It could also happen if the circuit is in contact with a conducting fluid such as saltwater. A short circuit can even happen through air if voltage becomes very high, enough to create an electrical "arc", overcoming the resistance of the air. In the worst case, a short circuit connects the positive and negative terminals of a battery or voltage source almost directly, with almost no resistance, and very high current results, which is dangerous. In other cases, the short circuit might not create any danger, because the path of electricity encounters resistance in another part of the circuit. However, the voltage difference across the short will be zero, and the voltage difference across the intended path between the endpoints of the short will also be zero. All the current will flow through the short, and none through the intended path. As a result that part of the circuit probably will not work.
