Question

please help me with the situation

I am finding difficult to solve numerical of power of electric current in a circuit. please help me with the formula and with an example ....... it's urgent guys ..........please.....

Answer 1

The current varies depending on the force behind the current and the resistance to flow. Current is inversely proportional to resistance. Potential difference, or voltage, is the electrical potential energy per coulomb of charge. ... The unit for measuring resistance is the ohm (Ω).
Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).
