Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit."

<<>>

if resistor exists, resistance decreases

according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance

it means as current increases, voltage increases.

resistance increases, current decreases so as voltage

if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter

When the resistance in a circuit increases what happens to the current flow?

"Ohms Law" defines resistance (R) as the the ratio of voltage (V) to current (I).R = V/IIf you move those variables around, you can get the formula:I = V/RSo you can see that when resistance increases, current flow will decrease.CommentResistance is most definitely not defined as 'the ratio of voltage to current', although that ratio may tell you what it happens to be.Resistance isn't a variable in the Ohm's Law equation. It is a constant because it is unaffected by either current or resistance.


What happens when a part of a parallel circuit is disconnected?

current decreases and resistance increases


What is the relationship among voltage current and resistance in a circuit?

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)


What happens to the generated voltage of a self excited generator if shunt field resistance is greater than the critical resistance?

When voltage increases what happens to current?

Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit."AnswerIf the voltage across a circuit increases, then the current will increase too. If the ratio of voltage to current is constant for variations in voltage, then the circuit is described as being 'linear' and is obeying Ohm's Law; if the ratio of voltage to current changes (as it would, for example, with tungsten) for variations in voltage, then the circuit is described as being 'non-linear', and is not obeying Ohm's Law. This is because Ohm's Law is not universal, and only applies to certain materials; in fact, most materials and electronic devices do not obey Ohm's Law.

What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?

If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.


What happens with electric current when applying the same voltage the resistance of the circuit is reduced?

As the resistance is reduced across the same voltage, the current increases.


What happens to current flow if circuit resistance increases and voltage remains the same?

nothing


How does the ac resistance of a diode change as the voltage increases?

When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.


What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?

If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance


What is the relationship between resistance and voltage in an electrical circuit?

In an electrical circuit, resistance and voltage are directly related. According to Ohm's Law, voltage is equal to the product of resistance and current. This means that as resistance increases, voltage also increases, and vice versa.


What does the voltage vs resistance graph illustrate in terms of the relationship between voltage and resistance?

The voltage vs resistance graph shows that there is a direct relationship between voltage and resistance. As resistance increases, the voltage required to maintain the same current also increases. This relationship is depicted by a linear graph where the slope represents the resistance.


When resistance decreases what happens to current?

Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases


Does the current ina circuit increase with increase in temperature?

Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.


Is voltage directly or inversely proportional?

Voltage is directly proportional to current, meaning that as voltage increases, current also increases and vice versa, as per Ohm's Law. However, voltage is inversely proportional to resistance, meaning that as voltage increases, resistance decreases and vice versa.


How does loading effect affect flow of current?

Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.


What happens to the voltage if the current increases?

Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
