Current and power relation
WebApr 7, 2024 · Power Resistance Relation. The relationship between Power and Resistance can be expressed in two following ways: 1. P = V 2 R. Where, P is the Power and we measure it in watts or W. R is the resistance measured in ohms (Ω). V = the potential difference applied across the ends of the conductor and is measured in Volts or … Web8. Power is P = I V. You can only relate it to resistance if you decided to fix one and replace the other by Ohm's law. Ohm's law states that voltage across a resistor is linearly proportional to the current flowing through it, …

The power will remain the same for a particular load as we are not changing the load. so if we increase the voltage, the current will decrease to make the net power consumed …
WebFeb 6, 2024 · The water in the river and in a hose relates to the relationship between voltage, current, and resistance in a circuit. In the water-hose analogy, the pressure … Webgle to each other. Net torque from current in phase with the induced voltage and torque component with no net torque, just vibration, from current at 90 deg. phase angle. Notice that the torque equation implies a relationship between the size of the rotor and the mechanical power that can possibly be delivered to the load. The mechanical power is 0
WebElectrical Energy: The Watt. Electrical Power is the product of the two quantities, Voltage and Current and so can be defined as the rate at which work is performed in expending energy. We said previously that voltage provides the work required in Joules to move one Coulomb of charge from A to B and that current is the rate of movement (or rate of flow) …
