Electronics Engineering

The voltage measured across every component in the circuit would take on

the opposite polarity from what it was originally. If there are any diodes in

the circuit, then current might stop flowing in some branches where it formerly

existed, or start flowing in branches where there was no current before.

By a DC power supply that runs at 230 volts AC. Basically, you need a full wave rectifier (4 diodes) to convert AC into all positive voltage. Then you need capacitors to smooth out the ripple and then various resistors to reduce the voltage.

If the AC adapter gives too little voltage, the electronic device will probably not work. If it gives too high a voltage, you will probably burn out the electronic device, which will have to be replaced or rewired. If the AC adapter is too weak (provides less milli-amperes than the device needs), the AC adapter can burn out.

In summary, you need to check: (a) that the adapter should have the correct voltage, and (b) that it provides the required amount of milliamperes (or more) for the device.

97 k ohms is equivalent to 97,000 ohms. Just multiply the value in kiloohms by 1,000 to convert it to ohms.

The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.

A; The base must be positive with respect to the emitter this condition will allow collector current to flow from collector to emitter. If the transistor manage to get saturated the current can flow in both direction. as a switch

The current rating for a 48 VDC contact relay can vary depending on the specific model and manufacturer. It is recommended to check the datasheet or specifications provided by the manufacturer to determine the exact current rating for the relay you are using.

It is a Ground Fault Circuit Interrupter or GFCI. It can either be equipped in your electric panel as a GFCI breaker, or in a GFCI outlet which also lets you extend the GFCI protection to other outlets "down the line" from the GFCI outlet.

It is connected across the hot and neutral if it's voltage is 120 volts. There are two terminals on the back of a panel mount frequency meter. Line voltage to one terminal and the neutral wire to the other terminal. The working voltage will be on the meter's nameplate which is usually located on the side of the device.

This is a trick question. A transformer transforms voltage and currents. The magnetic field strength of 15 Newtons (a measurement of force, or power) is not changed - in other words what you put into a transformer (in terms of power) you get out the other side (minus losses). so 15N in, 15N out.

You can also think of it this way: voltage is applied to the primary side, which induces a magnetic field. This magnetic field induces a voltage in the secondary side. So the magnetic field produced in the primary side is the same magnetic field that produces the secondary voltage. Thus the answer is in the question - the magnetic field is 15N (there's only one).

A switch in circuit symbols is represented by a break in the line with a gap or by a line that can be closed to complete the circuit. It typically looks like a gap that can be closed or opened to control the flow of electrical current in a circuit.

The magnetic field lines will form concentric circles around the wire, with the direction of the field lines being clockwise when viewed from above the wire.

Maybe... Electricity flows from a high potential to a low potential. Depending on where you have your high and low points it could look like its going clockwise but it really is only going from a high potential to a lower potential (normally ground)

Transformers work on the induction principal of the flux of the primary winding cutting the wires of the secondary winding. The amount of turns in the primary in relationship to the amount of turns in the secondary is the transformers winding ratio. This ratio is what governs the voltage value of the secondary winding.

A battery has a potential difference between its terminals due to a build-up of charge separation (positive and negative terminals). This potential difference can act as an electron pump by causing the flow of electrons from the negative terminal to the positive terminal through an external circuit, thereby generating electrical energy.

Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.

The potential difference (voltage) between the ends of the branch, and the

resistance of the branch.

In a simple parallel circuit, the voltage is usually the full power supply, so the

main thing to note is that none of the other parallel branches has any influence

on the current through the parallel branch of interest.

The power in the circuit can be calculated using the formula P = V x I, where P is power, V is voltage, and I is current. In this case, the voltage is 6 volts and the current is 0.5 amps, so the power in the circuit would be 3 watts (6 volts x 0.5 amps = 3 watts).

A series regulator maintains output voltage by adjusting its resistance to compensate for changes in input voltage or load current. It compares the output voltage to a reference voltage and regulates the voltage by adjusting the series pass device to ensure the output remains constant. This feedback loop continuously monitors and adjusts the output voltage, providing a stable output despite variations in input or load.

The decrease in resistance of alloys with temperature occurs because as temperature increases, the atoms within the alloy vibrate more vigorously, causing increased collisions between electrons and atoms. This increased atomic movement disrupts the orderly flow of electrons, leading to a higher resistance.

Alpha direct current (DC) is the current consumed by electrical equipment when they are idle or in standby mode, while beta DC is the current consumed by electrical equipment during their operation. Alpha DC is also known as standby power consumption, whereas beta DC is related to the active power consumption of the device.

To calculate the current, you can use the formula: Current (I) = Power (P) / Voltage (V). In this case, 60 watts divided by 120 volts equals 0.5 amperes. Therefore, a device operating at 60 watts on a 120-volt circuit would draw 0.5 amps of current.

False. The primary job of the distributor is to transport electricity from the transmission system to the distribution system and then deliver it to end users at lower voltages. The conversion of voltage levels is typically done by transformers at substations, not by the distributor.

It doesn't always do so, but it does, in the case of an electron current.

"Conventional current" is, by definition, the equivalent of a flow of positive electric charge. So, if a current consists of positive carriers (e.g., holes, or positive ions), the conventional current flows in the same direction as the current carriers. On the other hand, if the current consists of negative carriers (like electrons - the most common carrier for electric current), the electrons flow in one direction, but the conventional (positive, fictitious you might say) current flows in the other direction.

On a macroscopic scale, it is often useful to forget about the actual current carriers; for example, an electron current flowing to the left, and a current of positive ions flowing to the right, will have the same effect on a magnetic field.
