Switch ELECTRICALLY SAFE between 3 resistive loads (16 A each) on a 16 A line
How to switch 3 resistive consumers (heaters), each having a current consumption of nearly 16 A alternate & ELECTRICALLY SAFELY (German standards)?
So that only one of them heats at a time and the ...

DC-DC buck converter inductor current
Draw a simple dc to dc buck converter fed with dc voltage of constant magnitude (= E). The
converter supplies a resistive load (=R). Draw the shape of voltage waveform across the
freewheeling diode. ...

What happens if a ceramic power resistor is heated well past its rating?
What would likely happen if a ceramic power resistor was powered well over its power rating (for test/learning purposes and likely buried inside a bucket of sand)? By "well over", I mean 10 ...

Control power through a resistive load from a DC source and achieve low current peaks
I want to control the power through a resistive load from a DC source and achieve low current peaks. The use case is 0-1000VDC and 0-15kW (not for the entire voltage range). All other parameters and ...

How do I calculate the real power curve of a PWM resistive load supplied by rectified AC?
When AC is put through a capacitor filtered full wave rectifier, the output voltage is ~1.414 x RMS input voltage for zero load, and nominally equivalent to the RMS voltage when connected to a pure ...

Multipole Network Power Calculation
How do we calculate the DC power consumption of a multipole resistive network, if we know the currents of all the poles (pins) and all the voltages between the poles?
Let's say for example, that we ...

Which relay will last the longest?
I'd like to control a 20 amp, 240 volt AC resistive load with a heavy duty contactor.
The contactor I have is a Siemens 3TX7130-0DB03 rated for 30 amps, and DPDT. I was originally going to switch ...

60VAC resistive load (heater) on 220VAC?
I need to run a ceramic fiber heater (Watlow part number vc401a06a, datasheet) at 220VAC. This particular part is rated at 60VAC, for 220W. Can I safely use this on 220VAC, if I'll be controlling it ...

Is a protection diode needed for a resistive load?
In some applications a flyback diode is added parallel to the load. Is that because the switching causes reverse voltage for inductive loads? What if we have a resistive load instead? Do we still need ...
