No, even though these are parallel circuits, the voltage drop across each device is not the same in house hold circuits, or anywhere, for that matter. Different devices pull different currents. A toaster, for instance, pulls many times what a light bulb pulls. Since wires do not have truly zero resistance, those differing currents result in different voltage drops across the wires that lead to the devices. That small voltage drop in the wires results in a different voltage drop across each device, even though the device/wire is connected to the same voltage source.

Explain the advantages and disadvantages of connecting resistors in series in terms of currents and voltages?
For an electrical device, such as a lamp for example, to operate at its rated power, it must be supplied with its rated voltage. If several such devices are to be connected to the same circuit, the only way to achieve this requirement is to connect the devices in parallel (because the same voltage appears across each branch of a parallel circuit). Furthermore, with parallel connections, if one device should fail (or simply get switched off), all the other devices will continue to operate normally. These are the two reasons why most practical circuits are parallel circuits.Series circuits are less common but can be used for some lighting circuits (e.g. Christmas decorations) in which case the supply voltage is distributed equally across each of the lamps, which then have appropriately-rated voltages. For example, you may have twenty-four, 10-V lamps, connected in series across a 240-V supply.
What will happen if intrinsic standoff ratio of UJT is doubled?
If the intrinsic standoff ratio (η) of a Unijunction Transistor (UJT) is doubled, it will alter the operating characteristics of the device. Specifically, a higher η indicates a greater proportion of the total voltage across the device that can be used for triggering the UJT. This will result in a wider range of trigger voltages and may affect the stability and sensitivity of the device in applications such as oscillators or timing circuits. Overall, the performance and response characteristics of the UJT will change, potentially allowing for different operational behavior in electronic circuits.
Advantages of current transformer?
A CT allows:heavy currents to be measured using conventional ammeters, andelectrically-isolates the ammeters from high-voltage primary circuits.
What is FET?
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
Transistor is a linear or non linear circuit element?
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
Is line voltage understood as any voltage?
Line voltage is understood as the voltage that the device or appliance needs to operate on. It is also referred to as the devices working voltage. Once the proper line voltage or working voltage is applied to the device it may be transformed to different voltages for different internal component circuits.
What is the voltage across a device that draws 2A and dissipates 12w?
The voltage across a DC device that draws 2A and consumes 12Wh/h is 12/2 or six volts.
How do you comfirm thyristor condition?
A thyristor if conducting will have a very small voltage drop across if not then the rail voltage will be evident across the device
What is needed to calculate the voltage across a device?
you calculate a voltage circuit by taking it apart and findng the circuit and calculate the voltage and then resible it.
What is the use of offset null pin in integrated circuits?
Pin used to eliminate the effect of internal component voltage on the output of the device.
Is zener diode a voltage amplifier or currentlimitig circuit or osilator circuit?
The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
Can we use transformer as a generator?
No. Transformer essentially can step up or step down voltage or provide same voltage across the secondary side. It can not generate voltage on its own. Generator is essentially a rotating device. Transformer is a static device.
How is voltage measured in electrical circuits?
Voltage in electrical circuits is measured using a device called a voltmeter. The voltmeter is connected in parallel to the component or circuit being measured, and it provides a numerical value in volts that represents the electrical potential difference between two points in the circuit.

membrane voltage gated ion channels open and close with changes in the membrane potential

What is the open circuit potential difference?
Of what ? ! ? It's typically a few volts DC for a battery, 120 volts AC for a household outlet in North America, either zero or 5 volts DC at the output of a TTL logic device, and anything at all for various kinds of oscillators, drivers, or power supplies.
