How does the technique for measuring current with DMM differ from measuring voltage?
Well, measuring current with a Digital Multimeter (DMM) requires breaking the circuit and inserting the meter in series to measure the flow of electrons. On the other hand, measuring voltage involves placing the DMM in parallel across the component to measure the potential difference. Both techniques are important for understanding and troubleshooting electrical circuits, and with practice, you'll become more comfortable and confident using your DMM.
What else can I help you with?
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
How do power cords differ?
Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.
Are watts in 12 volt the same as 120 volt?
Watts measure power and are the same regardless of voltage; they are calculated using the formula ( \text{Watts} = \text{Volts} \times \text{Amps} ). Therefore, if you have a specific power requirement, the current (amps) will differ based on the voltage. For example, a device that uses 120 watts will require 10 amps at 12 volts, but only 1 amp at 120 volts. Thus, while the wattage remains constant, the current varies with voltage.
Why do the reading differ for increasing and decreasing values of the lamp voltages?
at the time of decreasing lamp voltage as the temperature is already high the gas in the lamp is already in ionized state leading to different resistance ,but when increasing voltage the gas is not in ionized state it ready to ionize ,so there is slightly variation in resistance . :)
What is the percentage voltage drop for feeders?
In the CEC (Canadian Electrical Code) voltage drop for feeders is stated in rule 8-102. Voltage drop in an installation shall not exceed 3% in a feeder or branch circuit. This percentage may differ in the NEC (National Electrical Code).
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
What will the current be on a hand held meter on a three phase motor if you clamp to two leads?
No way to tell. first off odds are you're measuring voltage rather than current, but apart from that the value would differ with your grid service and the rating of the motor
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
What happens to voltages and currents when there are passive elements connected in series and in parallel?
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
In a series circuit how does the current differ at different places along that circuit?
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
How is Mexico's education differ from the US?
different measuring
Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
Why parallel connection is most commonly used in your home?
In parallel connections voltage will be same in all paths, only current will differ. That's why its widely used in home connections
How did Renaissance art differ from earlier periods in terms of painting technique?
Renaissance art differ from earlier periods in terms of painting technique Renaissance artists used oil paints on dry walls.
How does a static discharge differ from an electric current?
It doesn't differ at all, an electric current is electricity that is moving in a current and when static electricity is discharged from an object it creates a current from one object to another
How does the non-inverting amplifier differ from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
