by using voltmeter
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
A possible/probable unit is Watts.
adding resistors to a string will have the effect of decreasing each resistor voltage drop.
v of what? v across what? v measured from what 2 points? v across the coils? v across the resistor? v across the coils and resistor? v across the battery? v across the battery and coils? v across the battery and resistor? or are you asking what v stands for? v stands for voltage.
The voltage across the resistor at the instant in the circuit where Vab is measured is equal to the potential difference between points A and B.
the potential difference across the single 4ohm resistor is 230volts.
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
Connect a power source to the resistor (+ve terminal to one side of the resistor and -ve terminal to the other) then connect a voltmeter in parallel with the resistor. The reading on the voltmeter will provide a measure of the potential difference across the resistor (ie: the voltage drop across it).

In parallel.
22ma. E=R/I
A possible/probable unit is Watts.
Work it out yourself. PD=P/I, Where PD=Potential Difference, P=Power & I=Current
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
