According to Ohm's law i.e. E=IR. When we increase resistance, keeping current constant, voltage will increase as in the above formula since E and R are directly proportional.

What will be the voltage drop when diode and resistance are used in series in a circuit?
voltage drop deviding accure
If you have two 75 ohm resisters one 150 ohm resistor and one 300 ohm resistor in a series circuit which one will cause the largest voltage drop?
Ohms law is: V = I x R (voltage = current x resistance) ... therefore the larger the resistance the larger the voltage drop across that resistance.
In a circuit where is the voltage drop?
In a circuit, the voltage drop is located wherever there is resistance. Ohm's law: voltage = resistance * current; so without resistance there can be no voltage drop, with resistance there is.
How can voltage drop be computed for a resistor?
Ohm's Law: Voltage = Current times Resistance
What would be the effect on the voltage level at the load if the distance between the electrical supply point and the load appliance is increased?
As the resistance in the wire increases due to the longer length the voltage drop across the wire resistance increases. This leaves less voltage across the load. To overcome this voltage drop usually a larger size wire which has less resistance is used. A safe nominal figure for voltage drop is to keep it at 3% of the line voltage.
Why does higher resistance have a larger voltage drop across it?
In a d.c. circuit, voltage drop is the product of resistance and current through that resistance.
What is the voltage drop using?
Voltage drop is caused by circuit resistance
What is the meaning of a good conducter of electricity?
A good conductor will pass electricity with little or no resistance. Resistance will cause the voltage to drop as the current increases. The least resistance will cause the least drop in voltage and is therefore a good conductor.
What is IR drop?
IR Drop means voltage drop. As voltage drop across any resistance is product of current (I) passing through resistance and resistance value(R ) , it is often written as IR drop.
What would cause high voltage drop readings?
High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
What effect does it have on the voltage drop in an electrical cable if the resistance of the cable is decreased?
It will decrease the voltage drop.
What will be the voltage drop when diode and resistance are used in series in a circuit?
voltage drop deviding accure
If you have two 75 ohm resisters one 150 ohm resistor and one 300 ohm resistor in a series circuit which one will cause the largest voltage drop?
Ohms law is: V = I x R (voltage = current x resistance) ... therefore the larger the resistance the larger the voltage drop across that resistance.
What is a IR drop across a resistance?
IR drop across a resistance is voltage. The letter I means current, and the letter R means resistance. Current times resistance, by Ohm's law is voltage.
Where does the unintended resistance result?
The unintended resistance results a voltage drop
Why resistance drop occurs in a conductor?
All conductors have some amount of resistance associated with them. There is voltage drop along the length of a conductor because the potential energy of the voltage is lost to heat losses (I^2 *R) due to this resistance. The more resistance, the more voltage drop. The current is set at a given voltage and power level.
What are the symptoms of a loose battery terminal?
A loose battery terminal will cause intermittent power supply, high resistance and heating. A high resistance will cause a voltage drop, as more current is drawn from it.
