∙ 11y agoAssuming that the resistance of the load stays constant - and that nothing else but the voltage changes - as the voltage applied to a load increases the power taken by that load must also increase.
This result comes firstly from Ohm's Law: current = voltage / resistance
and secondly from the Power Law: power = voltage x current.

∙ 14y agoAs you increase th evoltage you increase the current if the load remains constant.
By Ohm's Law Voltage = Current x Resistance.

What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
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.
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
Does reactance increase with an increase in inductance?
Inductive reactance case of ac) is equivalent to resistance (in case of dc) for inductors.So if resistance increases current decreasesas well as if inductive reactance increases current decreases
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
What happens to the amount of current in a series circuit as the number of batteries increase?
it 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.
If resitance stays the same current increases dose the voltage increase?
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of the circuit. I = E/R.
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.
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.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
What happens to voltage when resistance increases?
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
How is the current affected by the number of bulbs?
As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
Why does energy increase when voltage increases?
If we increase the voltage by adding extra cells or batteries we give the electrical charges more energy and so, the current flowing around the circuit increases.
