What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst
What happens if there is a break in a series circuit?
The series circuit becomes an open circuit because there is no remaining path.
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
In a circuit with resistive and inductive load what happens to the power factor as the resistive load increases?
The PF will increase
What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst
What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
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
What happens when both 110v leads are applied to one side of a 220v electric motor?
The breaker will blow because you are effectively causing a short circuit.
What happens to voltage and resistance when increasing and decreasing is taking place?
As Ohm's law states; Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Can a magnetic field affect the performance of electrical circuits?
You better believe it can, but only if it's changing, otherwise the magnetic field can just pull or push the electrons in the circuit towards or away from it, but it can't slow them down. If the magnetic field is changing, a phenomenon called inductance happens. Inductance is an applied current to a circuit by a changing magnetic field. As you might imagine, an additional applied current to a circuit can definitely change the circuit's behavior and alter its performance.
What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
What is alternated current?
That refers to a current in which the direction of flow changes continuously. In household current, this usually happens at 50 or 60 cycles per second (depending on the country), but the definition of alternating current can include just about any other frequency, as well.
What happens when a circuit closes?
when a circuit is closed, electricity can move though it.
What happens when a circuit is closed?
when a circuit is closed, electricity can move though it.
What happens if current flows through 2 parallel current in the same direction?
With the possible exception of some circuits that have inductance and capacitance in parallel and are excited by a pulse or an alternating voltage, the currents in two parallel branches of a circuit are ALWAYS in the same direction.
