How the current are related to the power supplied by the source?

Power (watts) is voltage times current.


What is controlled voltage?

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.

One way to make current is to use a what?

You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R


Can you calculate power by multiplying voltage and current?

Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).


How do I calculate wattage?

To calculate wattage, you need to multiply the voltage (V) by the current (I). The formula is: Wattage (W) = Voltage (V) x Current (I). This formula applies to electrical circuits where the voltage is known and the current is flowing.

What do you understand by electric current?

electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.


What does ac stand for the mains voltage supplied in the UK?

AC stands for Alternating Current and DC stands for Direct Current.


How do we calculate?

V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
