Step 1

Given:

Resistance of the component = 17 ohm

Maximum Power rating = 14 W

Step 2

Calculating the amount of maximum current th... help_outlineImage TranscriptioncloseAs we know, power is related to resistance and current as P 12R P VR Or I (1) So, if we know the maximum power rating of any component, then we can find the maximum current flow through the component by using equation 1 Hence, maximum current that can flow through the given compponent, 14W P max max 17Ω R I =0.91.4 max fullscreen
