increasing resistance and keeping current constant
What else can I help you with?
What actions will always increase voltage?
increasing resistance and keeping current constant
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Does increasing the voltage to an electric heater increase the amperage it draws?
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
Will the resistors ohmic value increase if you increase the voltage?
No.
Can a voltmeter increase its voltage?
no
What is the name of the component that is used to increase or decrease alternating voltage?
A transformer is used to increase or decrease alternating voltage.
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
Can a voltmeter increase voltage?
No, a voltmeter measures voltage in a circuit but cannot increase it. It is a passive device that is simply used to read the voltage at a specific point in the circuit.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
