There is insufficient information in the question to properly answer it. You need to provide more information, such as the voltage across resistor four, or more details about the rest of the ciricuit. Please restate the question.

Four 1000 ohm resistor are connected in series across a 4V supply?
Four 1000 ohm resistors in series have an effective resistance of 4000 ohms. Across a 4 volt voltage source, they would have a current of 1 mA, with a power dissipation of 4mW.
Why you need 250 ohm resistor in hart?
The resistor doesn't have to be 250 Ohms, anything from 100-600 will work equally well. The power supply is a low impedance to the hart signal shorting it out. Adding the resistor raises the impedance so that the signal can be detected by the calibrator. A small reactor would also work.Ohms law states that a resistor must be present with current to receive a voltage (V=IR) this resistor converts current to voltage which is used as a digital voltage signal. (1-5 V).The HART protocol uses 1200 baud Frequency Shift Keying (FSK) based on the Bell 202 standard to superimpose digital information on the conventional four to 2OmA analogue signal.Hope this may help ful....Sudhan.Sshansudhan@rediffmail.com
Will a DC to AC inverter power a 13.5 Amp motor?
It depends on the inverter. Keep in mind that the average starting current of a motor is four times its running current, so the inverter would need to be able to handle a 54 Amp transient. (Or higher, depending on design margins.)
What will happen to the current if the voltage is multiple four times?
it will turn into a cupcake with 3 currents on it.
What happens to the direction of the magnet field about a straight section of wire when the direction of the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.
Current through a resistor doubles power consumption does what?
Four times as much.
What control operates the fan motor?
Well, the fan switch... if it has, say, four settings, then the first three settings simply select which resistor the current runs through, and the fourth typically is a circuit with no resistor.
To reduce the voltage, I need to change the voltage of 5v to 4.5v, I use a 30 ohm resistor, how many watts of resistor should I use?
To calculate the power rating of a resistor required to drop the voltage from 5V to 4.5V using a 30 ohm resistor, we can use the formula: Power = Voltage Drop x Current The current flowing through the resistor can be calculated using Ohm's law: Current = Voltage Drop / Resistance Substituting the values we get: Current = (5V - 4.5V) / 30 ohms = 0.0167 A (rounded to four significant figures) Now we can calculate the power required: Power = (5V - 4.5V) x 0.0167 A = 0.00835 watts So a resistor with a power rating of at least 0.00835 watts (or 8.35 milliwatts) should be sufficient for this application. However, it is recommended to use a resistor with a slightly higher power rating to ensure that it can handle any temporary power surges or variations in current that may occur. A 0.25 watt resistor should be suitable for this purpose.
What is the resistor color code and how is it used to identify and select resistors?
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
What are the steps to running the chkdsk utility on a PC?
There are four steps to running the chkdsk utility on a PC. You can learn exactly how to go through these four steps by going online to WikiHow- run chkdsk. They will walk you through the process.
