If part of an electric circuit dissipates energy at 6 W when it draws a current of 3 A, what voltage is impressed across it?

P=6w
I=3A
V = ?

2 volts

Explanation:

Power=current x voltage

6=3 x voltage

Divide both sides by 3

6/3=(3 x voltage)/3

2=voltage

Voltage=2volts

d eras and periods

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
