Confused about usage of Ohm's law & Kirchhoff's laws to solve a circuit

Your "wrong" equation \$120V = I_0\times 10\$ is wrong because: Ohm's law relates the current through a resistance R to the voltage across that same resistance R. Perhaps what you've done ...

Confused about usage of Ohm's law & Kirchhoff's laws to solve a circuit

You need to find the voltage across the 10 ohm resistor before applying Ohm's law; it's not 120V. You also need to know this voltage for part b) of the problem, to determine the power produced by the ...

Parallel circuit calculations

I'm going to make a huge guessing leap about this lab work and imagine that you are dealing with a tungsten lamp and that your lab trainer made a resistance measurement of the lamp, when cold; but you ...
