    Dimplex CXL 18 Storage Heater - Resistor Question

    Hi, I'm just a DIY're but I'm OK with basic electrics. Grateful if anyone could help me with the location of where the double resistor is wired to. I had to replace the control panel on the convector side of the heater and decided to also replace the elements as one had stopped working over...

    Resistor across L-N in an adapter box. Possible or asking for trouble?

    If I place say an 80 Ω resistor across L-N, would that generate a load of approx 2.8A. I’m looking to create an artificial load of a socket circuit so I can locate the current at the DB using a clamp meter. Used to use plug in 3kW heaters but not an option anymore, also definitely not able to...

    Load resistor ..........

    Hello to everyone, and excuse me for the stupid question :) I have a valve in my cooling system that I need to disable every now and then so my acc heater heats the engine as well as the cabin. Anyway. The valve is 13ohms has a consumption 1amp and runs on 12v.Is it all right if I connect a...

    How to check the Wattage of a scrapped resistor?

    - I want to know what these -unknown- resistors Wattage are !? First of all, they are scrapped. Then, we really dont know in what part of the circuit they had sit, in the gate of the circuit where high power was entering? or in the core of the circuit, where the power didnt matter that much...

    Can I eliminate dimmable LED flicker by wiring in a resistor?

    I am using 3x dimmable bulbs (LAP SES Candle LED Light Bulb 470lm 5.9W 4 Pack - https://www.NoLinkingToThis/p/lap-ses-candle-led-light-bulb-470lm-5-9w-4-pack/9586t) with this dimmer switch (https://www.amazon.co.uk/Lieber-Dimmer-Rocker-Switch-Trailing/dp/B088P61884). As the dimmer is turned down...

    LED resistor values.

    Hi, I am just wondering if you can please help me. I have four LEDs connected to a 9 volt battery. They have little circuit boards in them. They will run between 9 volts and 15 volts. I have them wired up in parallel to a 9 volt battery. They work fine. They are drawing 30mA at 9 volts. So I...

    Capictor and resistor across a flow switch

    Hi I am reconfiguring a hot wash unit and need to use a flow switch as in attached files. It controls a light powered relay and timer module I can use a separate relay to control the the others, does this count as a inductive load? We are talking 25v ac the switch is a reed switch rated at 3A...

    UK Resistor for volt drop

    Hi Guys I was asked to look at a twin extract fan system that was showing a trip fault after checking that both fans ran by temporarily bypassing the fan controller after further investigation I found that a resistor was in serious with a bridge rectifier The dc side of the rectifier is...

    UK What kind of resistor as there are so many?

    Hello and thanks for taking a look at my question. Basically I am struggling to source some resitors that I need to connect into a circuit so my instrument can read realistic measurements on a small rig. I need 1ohm, 2ohm, and some 0.5ohm, 0.2ohm and 0.1ohm resistors. When I ring RS they say...

    Old Campervan Aux Battery Charging components, what is this thing!?

    So I've been using a friends Toyota Hiace Campervan (1989, high roof) I've just upgraded to a 105Ah battery from a 65Ah Solar charging works as expected, but the charging from the main or alternator isn't doing enough to keep it topped up. When the ignition is on (before the engine has...

    Installing a resistor on a side mirror socket

    Hey, I'd like to ask for help, what should I use to avoid the side mirror turn signal warning? I recently installed dynamic side mirror turn signals on my Audi A4 B8 2009, has been getting an error since (for both sides). I was thinking about installing a can-bus resistor kit on the sockets...

    Braking Resistor

    What is a Braking Resistor Used For? The main purpose of brake resistance is to help realize overhaul and engine braking by dissipating rheostatic resistors as heat and absorbing regenerated braking energy. In summary, the purpose of brake resistance is to slow down, control, or quickly stop an...

    Resistor getting hot

    Hi all, Hopefully someone can help me out here. Ok, so I have: 9 x 1w LED, its 12v, 300ma, 3,4v. 9 x 3w 33R resistor. Power supply 12v, 200ma (testing with this one but i intend to use larger ma when all 9 leds are in use). I believed this resistor to be good enough (its a fair size) to cope...

    How to get my ambient surround to work?

    Hi, I have a Ford Fiesta mk8. I brought some ambient surrounds 3 for my car expecting they may work as on the website it states it only works on the st fiesta. I wired the positive and negative direct to the battery as stated, I then wired the indicator cable to the right and left indicators...

    Why current sensing resistor is so tricky ?

    Hi I didn't understand why when i short the current sensing resistor , the psu/adapter become unstable (voltage dropping and noise) and forever, even if i restore the original resistor !!
