एक कुंडली (coil) का प्रतिरोध 44 Ω है। यदि इसे 220 V की आपूर्ति से जोड़ा जाता है, तो कुंडली द्वारा खपत की गई शक्ति कितनी होगी?

If a charge of 3 C is moved across a potential difference of 15 V in 3 seconds, what is the power developed in the process?

An electric heating element has a resistance of 50 Ω. If it is connected to a 250 V electrical source, determine the amount of power dissipated by the element.
