The Electric Power and Efficiency Calculator will calculate the:

The output power delivered by a circuit component is W [Watt] |

The input (total) power of the circuit delivered by the battery is W [Watt] |

The efficiency of the electric circuit is % [Percent] |

P_{o} = I × ∆VP _{o} = × P _{o} = |

P_{i} = I × εP _{i} = × P _{i} = |

e = × 100%∆V/εe = × 100%∆V/εe = |

Electric Power And Efficiency Calculator Input Values |

Electromotive force of battery (ε) V [Volt] |

Current flowing in the main branch of the circuit (I) A [Amp] |

Potential difference across the circuit component (ΔV) V [Volt] |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each electric power and efficiency calculation, the Electric Power And Efficiency Calculator will automatically calculate the results and update the Physics formula elements with each element of the electric power and efficiency calculation. You can then email or print this electric power and efficiency calculation as required for later use.

We hope you found the Electric Power And Efficiency Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe.

P_{o} = I × ∆V

P_{i} = I × ε

e = *∆V**/**ε* × 100%

This formula derives from

e = *P*_{o}*/**P*_{i} × 100% = *I × ∆V**/**I × ε* × 100% = *∆V**/**ε* × 100%
