Question

CLASS X :
How is power related to current and voltage ?(provide a derivation as well)

Answer 1

Answer:

power is directly proportional to current and voltage

Explanation:

P=W/t V= W/Q-> VQ=W

Replace

P=VQ/t I = Q/t

Replace

P = VI

so P prop to V &I

Answer 2

Answer:

The faster the water is flowing / higher the pressure can be equated to voltage. ... Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current (Watts (power) = Volts x Amps.

p equals to v I

What happens to power when voltage increases?

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Is power directly proportional to current?

Power is P=IV. ... Ohm's law states that voltage across a resistor is linearly proportional to the current flowing through it, or V=IR. This can be arranged to say that current is inversely proportional to voltage, or I=VR.
