A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
Increase the voltage across the resistor by 41.4% .
the potential difference across the single 4ohm resistor is 230volts.
You just stated that the voltage across the resistor is 15 volts, so that's your answer ! If the resistor is connected to a 15-V battery or to the output of a 15-V power supply, then a meter across the resistor is also across the power supply, and reads 15 volts. The current through the resistor is (V/R) = (15/2700) = 5.56 mA. The power dissipated by the resistor (and delivered by the battery) is (V2/R) = (225/2700) = 0.083 watt.
The resistance measured across the excitation terminals of the load cell, when the output terminals are open.
Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor. You need to measure or find the information of either I (using an ammeter) or V (a voltmeter).
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
Similar to the third wire on an RTD, 2 terminals are the current carrying conductors, 2 for the voltage. There will be a voltage drop across any current carrying connection. The voltage sense lines don't carry any current, so they accruately measure the voltage across the calibrated resistor/shunt.
The rule for voltage across each resistor in a series circuit is that the total voltage supplied by the source is equal to the sum of the voltage drops across each resistor. In a parallel circuit, the voltage across each resistor is the same and equal to the source voltage.
No. If a voltage is applied across a resistor, a current flows through it.
The protecting resistor is put in series with the LED so that you have a voltage divider - the supply voltage is split across the LED ( max 0.6v) and the remainder across the protecting resistor. So if your supply is 6volts, 5.4v will be across the resistor,
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Rheostat is simply a variable resistor. i.e., typically 3 contacts, either end of resistive element and slider contact that moves along resistive element. So, in old radios would typically be used as a volume control.AnswerA variable resistor may be used to control current, in which case it is called a rheostat. Or it may be used to control voltage, in which case it is called a potentiometer. In other words, the terms 'rheostat' and 'potentiometer' do not describe devices but, rather, they describe two applications of a variable resistor.As a rheostat, the variable resistor is connected in series with a load, and two of its three terminals are used -one of the fixed terminal and the slider terminal.As a potentiometer, the variable resistor is connected in parallel with a load, and each of its terminals are used. The two fixed terminals are connected across the supply, and one of the fixed terminals, together with the slider terminal, is connected across the load.

connecting the damping resistance across the terminals
Yes, it is possible to apply a voltmeter across a variable resistor. The voltmeter would measure the voltage drop across the variable resistor as the resistance changes. This can help in monitoring and adjusting the voltage across the resistor in a circuit.
