Generally the voltage is constant and current varies as per the load. Load can vary and hence current can vary. You are stating an abnormal situation, where in voltage increases while current remains constant. I am assuming a constant load situation then normally when voltage increases, the current tends to reduce since over all load remains same. If the voltage goes up beyond a limit the insulation fails and may lead to short circuit, equipment failure, shock and fatality

Use Ohm's Law equation I = E/R. If the current stays the same and the voltage increases then the resistance must also increase.


Using some values with a constant amperage value of 2 amps at 12 volts. I = 12/ 6 ohms = 2 amps,


Raise the voltage to 20 volts and see that the value of the resistance must also increase to keep the equation equal I = 20/10 ohms = 2 amps.


Again raise the voltage to 24 volts and see that the value of the resistance must also increase to keep the equation equal I = 24/12 ohms = 2 amps.


To answer the question, to maintain a constant current in a situation where the voltage becomes higher the resistance must also become higher.

What happens to electrical current and voltage in a parallel circuit as you add more bulbs?

Voltage remains constant; current increases.


What happens to the power in a circuit as the current increases?

P=VI If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant. If voltage decreases and current increases or vice versa, proportionally then P will remain the same.


How does current vary with the resistance in the circuit if the voltage is constant?

Inversely. As resistance increases, current dereases; given that the applied voltage is constant.


What is the voltage across diode carrying a constant current?

What increases when the resistance of an electrical circuit decreases?

Current increases if the voltage remains constant.


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.


If voltage changes in a ac circuit what happens to current?

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.


What happens to the current when the voltage is doubled and the resistance is constant?

I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.


How current increases when the load increases in a generator?

Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.


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.


What happen to the current when the voltage increased if the resistance are constant?

If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.


If the resistance in a circuit is doubled while the voltage remains the constant the current is?

It is halved. coz voltage=current * resistance
