Question

a device is connected to 100 V supply and it draws 8 A current. calculate the power consumption of this device.​

Answer 1

Explanation:

Remember:

● First formula of Power [P] = V × I

● Second formula of Power [P] = V²/ R

● Third formula of Power [P] = I² × R

Now, according to the given question

P = V × I

=> P = 100 V × 8 A

=> P = 800 Watts

Hence, the power consumed by the device is 800 Watts.
