Can you list three ways you can change the current in a circuit?
Increase, decrease, or remove the load <<>> Change the voltage and the current will also change in direct proportion, Ohms law.
How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
How would a meter be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
What two things are needed to make electrons move along a wire?
-- voltage difference (electromotive force) between the ends of the wire; -- conductive substance comprising the wire.
Describe how a meter would be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
What voltage would you expect to measure on a red wire from a power supply?
+5 VDC(Volts Direct Current)
Why you use current source?
Current source can be helpful in application where you want to measure very low resistence like a wire for example. The basic idea behind this is to fix the amount of current and then measure the voltage across the wire.
Which wire carries the voltage?
Electrical wire.
Is cat5 wire considered low voltage?
Yes. cat6 is low voltage / signal wire.
How do you know if a wire is carring current for the speakers in a vechiles?
With the system powered on and playing sounds measure the voltage at the speaker terminals with an AC voltmeter. If you measure voltage turn off the system and disconnect one of the speaker terminals and measure across the speaker with an ohm meter. If there is any significant conductance the wire is probably carrying current when the system is playing. Better yet take it to a competent technician.
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
How do you know the voltage drop of wire?
Voltage = Current x Resistance. To calculate the voltage drop of a piece of wire, you would have to know the current flowing in the circuit and the resistance of the wire. The resistance of wire depends on the material it is made of, the length, and the cross sectional area (also called gauge or AWG). Short thick wires have less resistance than long thin wires. You can look up the resistance of the wire on the Internet, and you can measure the current flowing by connecting an ammeter in series with the circuit. Multiply those two numbers and you will have closely approximated the voltage drop across the wire.
