What else can I help you with?
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
What does the voltage across a inductor do?
voltage across inductor create a flux. because of variation current developes an opposite emf.
Why voltmeter should have a very high resistance?
well a voltmeter measures AC and DC voltage. resistance is a term used only for DC voltage, A voltmeter uses a term called Impedance for AC, without it, when you measure across two terminals it would create a short circuit and would blow up the meter. it is basically a safety feature to prevent people from creating short circuits when measuring.
When biased correctly a zener diode acts as?
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
Why the output voltage from a transformer is zero if a direct current flows through the primary coil?
A transformer relies on AC current flowing through the primary to set up changing magnetic fields in the core. The field flows through the core and in to the secondary of the transformer, generating an AC current. The current must be AC, otherwise the magnetic field in the core of the transformer will saturate. In the same way, the armature of a dynamo or alternator must be moving in order to create a changing magnetic field to create current through the windings.
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
When can voltage be induced but not current?
"Induced" is the verb you are looking for. A current is induced in the secondary circuit by the current in the first changing, provided both conductors are close enough for the driving current's electro-magnetic field to enclose the second conductor. Note that word "changing". Direct current produces a field but that remains constant and does not induce a secondary current, as a.c. does.
Why does a low voltage circuit create more amperage than a high voltage circuit?
That depends on what you mean. If you mean why does a circuit which has a high voltage side and a low voltage side have a greater average current on the low voltage side, it is probably because of power conservation: P = IV. If this is not what you mean, you will have to be more specific!
How does a magnet create electricity?
A magnet can create electricity through electromagnetic induction. When a magnet moves near a conductor, such as a wire, it creates a changing magnetic field around the conductor. This changing magnetic field induces a current to flow in the wire, generating electricity.
Should a 24vdc circuit create arcing to use as a switch or signal?
Some voltage must be present but the current causes the arcing.
What is example of dependent source and independent source of voltage and current?
Boss its a circuit not a device, you can also create one of yours..... just use simple logic of voltage divider and current divider rules...-satendra.svnit@gmail.com
What is a passive element in a circuit?
A passive element is an element of the electrical circuit that does not create power, like a capacitor, an inductance, a resistor or a memristor.
Why do you use resistors and capacitors in a circuit?
resistors and capacitors are used in order to create a path for the current , for the resistivity of the current , for the storage of the current.AnswerResistors don't just 'resist' electric current, they create a predictable change in voltage (electric potential) from one side to the other, so they can be used to adjust the expected voltage level at each point in a circuit.In an electric circuit with an unchanging current and voltage, capacitors simply store current and wait for something to change.In the more common electronic case of a circuit with voltage fluctuations, each capacitor is effectively a high-pass filter -- it permits quickly-fluctuating voltages to pass through, but reduces or stops slowly-fluctuating voltages.
What happens when an electric current is interupted?
When an electric current is interrupted, the flow of electrons is stopped, causing the circuit to break. This can lead to the devices connected to the circuit losing power or shutting off. Additionally, sudden interruption of a current can create voltage spikes that may damage electronic components.
What components in a circuit try to .the electricity flowing through them?
Resistors are components in a circuit that try to limit the flow of electricity passing through them. They are designed to impede the current and create a voltage drop as a result.
What is such as battery that creates a potential energy difference in a circuit?
A battery creates a potential energy difference by separating positive and negative charges to create a voltage. This voltage difference creates an electric field that drives the flow of charged particles (current) through the circuit.
