How to convert electric power in watts (W) to energy in joules (J).You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities.Watts to joules calculation formulaThe energy E in joules (J) is equal to ...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
The moon is just entering the waning gibbous phase. In approximately how many days will it enter the waning crescent phase? (a) What is the average power consumption in watts of an appliance that uses 5.00 kW\cdoth of energy per day? (b) How many joules of energy does this appliance ...
Determine the number of calories to change 1 kg of 0^{\circ}C ice to 0^{\circ}C ice water. How many joules of energy does a 100-watt light bulb use per hour? The specific heat capacity of a metal is 761.53 joules per kilogram C. How much heat energy (in joules) is needed to...
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...
a 10-nanosecond pulse has an energy content of only 10 joules. To put this in perspective, the average microwave oven in one second generates 1 kilojoule, or thousand joules of energy. It typically takes about 4 minutes to boil a cup of water, which corresponds to 240 kilojo...

An energy-efficient lamp rated at 10 watts uses 10 joules of energy every second (because 1 watt means using one joule per second), so it would take it 37,800 seconds—about 10.5 hours—to use as much energy as our kettle uses in a single boil!
A thunderstorm is one of nature's most dramatic acts, and one of its most frightening. All thunderstorms produce lightning, every bolt of which releases around 1 billion joules worth of energy. That's enough to keep a 60-watt light bulb on for over six months. Lightning is so powerful th...
