What else can I help you with?
How do you decrease voltage in dc without decreasing amperage?
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
Why the armature current is increasing when the terminal voltage is decreasing?

What is ramp voltage?
Ramp voltage is a voltage that can be steadily increasing or decreasing.
What are the factors that influence the speed of the direct-current shunt motor with increasing load?
.The magnitude of the voltage and current of both the armature and shunt field coil. To decrease the speed when the load is increasing then increase the shunt field current while decreasing the armature voltage or current. To increase the speed while the load is increasing then increase the armature current while decreasing the shunt field current. The decreasing and increasing of these currents and voltages can be done by connecting a variable resistor in series or parallel with each of the armature and/or shunt field coil.
You are monitoring electric current in a circuit. you notice the voltage increasing this mean's that?
Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (E) and inversely proportional to the circuit's resistance (R).I = E/RAnother way of stating Ohm's Law is that the applied voltage (E) is directly proportional to both the current (I) and the resistance (R).E = IxR.So, if the voltage (E) is increasing, then either:if you know the resistance (R) is staying constant then the current (I) must be increasing - which you would see because you are monitoring it! or, if the current (which you are monitoring) is actually staying constant, then, for the voltage to be able to increase:the circuit's resistance must be increasing orthe increasing voltage could be caused by a combination of both increasing current and increasing resistance!
What would induce a greater electric current in a wire?
A greater electric current in a wire can be induced by increasing the voltage applied across the wire or decreasing the resistance of the wire. Both factors contribute to Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Increasing the voltage or decreasing the resistance will lead to a higher current flowing through the wire.
How can you increase a current in a wire?
Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.
How can the current in a conductor be increased?
The current in a conductor can be increased by either increasing the voltage applied across the conductor or decreasing the resistance of the conductor.
What happens to voltage and resistance when increasing and decreasing is taking place?
As Ohm's law states; Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
How do you change the current in a wire?
To change the current in a wire, you can adjust the voltage applied to the wire or change the resistance in the circuit. Increasing the voltage will increase the current as per Ohm's Law (I = V/R), while decreasing the resistance will also result in an increase in current.
Why does increasing voltage of a wire have the same effect on the current that decreasing the resistance has?
Increasing the voltage in a wire causes more electric potential energy per charge, which results in higher energy per charge moving through the wire, leading to an increase in current. Similarly, decreasing the resistance in a circuit allows for more charge to flow with the same applied voltage, resulting in an increased current flow.
What will cause an increase in current flow in a simple series circuit?
An increase in voltage or a decrease in resistance will cause an increase in current flow in a simple series circuit. This is because current is directly proportional to voltage and inversely proportional to resistance according to Ohm's Law.
Why increasing the voltage applied to a wire can have the same effect on the current in the wire that decreasing the resistance of the wire does?
Increasing the voltage applied to a wire will increase the electric field, which in turn accelerates the charge carriers (usually electrons) in the wire, leading to an increase in current. Similarly, decreasing the resistance of the wire allows more current to flow for the same voltage applied, achieving a similar effect of increasing the current. Both actions result in a greater flow of charge carriers through the wire.
How do you decrease voltage in dc without decreasing amperage?
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
What are two ways increase the current in the wire?
You can increase the current in a wire by increasing the voltage applied across it or by decreasing its resistance. Additionally, increasing the cross-sectional area of the wire can also help facilitate higher current flow.
Why do the reading differ for increasing and decreasing values of the lamp voltages?
at the time of decreasing lamp voltage as the temperature is already high the gas in the lamp is already in ionized state leading to different resistance ,but when increasing voltage the gas is not in ionized state it ready to ionize ,so there is slightly variation in resistance . :)
