First off, voltage and current are two completely different, yet related phenomenons.
Kirchoff's law states that Voltage = Current * Resistance (V=IR. So, to change the voltage in a given circuit while keeping current constant, simply change the resistance.
The ability of conductor to induce voltage in itself when the current changes is called inductive reactance.
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
RPS is only the voltage& power controlled device. it can only used for set the input for our wish A device which can change its output according to the voltage supplied to it is called a voltage controlled device.ex. a voltage controlled current source,or a field effect transistor. In a voltage controlled current source the output current changes as the voltage supplied to it changes.
A: The small base current will control the collector current flow by adding a resistor this changes of current flow will be evident as a voltage amplifier.
Voltage
how do you use ohms law express conductance in terms of current and voltage?
The ability of conductor to induce voltage in itself when the current changes is called inductive reactance.
Yes and no. As voltage changes, current changes, causing power to change, with the end result that temperature changes. Most resistors have a small temperature coefficient, so their resistance will change slightly as the voltage changes.
When a current flows through a capacitor, the voltage across it increases or decreases depending on the rate of change of the current. If the current is constant, the voltage remains steady. If the current changes rapidly, the voltage across the capacitor changes quickly as well.

If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
No. Power stays the same. Power is voltage times current. So, if voltage is doubles, current has be halved, less efficiency losses.
A transformer. it steps up / down voltage, and steps down / up current.
A transformer is a device that changes the voltage of an electrical current, either increasing or decreasing it depending on the design.
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.
The derivative of current with respect to voltage in an electrical circuit is called conductance, which represents how easily current flows through the circuit in response to changes in voltage.
