#10 is a bit misleading. Yes it makes no difference but the question asked what’s the best way…I’d rather have the 12 gauge first in case I unplug the 16 gauge for a power tool that requires higher amps.

If you have two 10w bulbs un series wont they draw half the amount of wattage each bejng 5w, still making total power consumed by the circuit 10w?
I got 9/10 except for this one…

Number 6 question is wrong in a series circuit the wattage would increase. Series circuits amperage stays the same voltage adds so if you have 2 10w bulbs connected to 120v supply then the bulbs would produce 0.1666 amps each a single bulb would be 0.0833 amps. the wattage would be 10w for a single bulb or 20w for two bulbs. a light bulb is a fixed resistance it will not reduce in resistance in a series circuit.

Yeah I got it wrong too. I should have taken the time to run the numbers in my head. Double the resistance halves the current. You then split the voltage drop across each load so you get half the voltage times half the current across each load. 1/2 X 1/2 = 1/4. 1/4 times 2 equals 1/2. Damn.

But seriously, I’ve listened to all your podcasts and I am a strong supporter. I am working on an electrical trainer for our new techs right now with basic circuits, and am also trying to put together a curriculum for a training program for the company. Glad to see like minds out there!

Start testing static pressure with the basic Testo 510 static pressure kit. Use offer code "getschooled" at checkout for a great discount

The Testo 550 is the best buy for a capable digital manifold on the market. Bluetooth enabled with two thermistor clamps it does a great job day in and day out. Use offer code "getschooled" at checkout for a great discount

The Testo 770-3 measures amps, volts, capacitance, temperature, wattage and power factor all in one Bluetooth enabled multimeter. Use offer code "getschooled" at checkout for a great discount

The Testo 605i Hygrometer and the 115i Line clamp are the perfect duo to "check the charge without gauges". Use offer code "getschooled" at checkout for a great discount

Prevent refrigerant huffing and theft as well as comply with local codes by using the Novent line of refrigerant locking caps

The Kickstart family of hard start kits use a potential relay and a start capacitor. We find them to be a great option for hard starting in after market service applications

A/C Leak Freeze from Rectorseal is the only leak sealant I have tested that I am confident will not harden and harm a system or your gauge manifold

We use the Safe-T-Switch SS1 and SS2 condensate switches on all of our jobs and they have never let us down

Fair enough

No, both TOGETHER will draw half so each would be 1.25W when in series.

Number 6 question is wrong in a series circuit the wattage would increase. Series circuits amperage stays the same voltage adds so if you have 2 10w bulbs connected to 120v supply then the bulbs would produce 0.1666 amps each a single bulb would be 0.0833 amps. the wattage would be 10w for a single bulb or 20w for two bulbs. a light bulb is a fixed resistance it will not reduce in resistance in a series circuit.

Hello Kevin. It isn’t wrong, it’s just deceiving because while bulb is marked with a wattage is is actually just a fixed resistor.

Ohms law shows us that as resistance increases amperage (and thus wattage) decrease

Yeah I got it wrong too. I should have taken the time to run the numbers in my head. Double the resistance halves the current. You then split the voltage drop across each load so you get half the voltage times half the current across each load. 1/2 X 1/2 = 1/4. 1/4 times 2 equals 1/2. Damn.

Bryan Orr, you’re my hero.

I’ve never been a hero before… it feels… weird 🙂

Thanks for the support man, feel free to use anything we have on the site.

it been a while

Yes…series vs parrellell rules…
