Circuit with time relay for continuous current?

ByMarkusm11

Hello everyone I only have a theoretical question to estimate the effort involved: In the basement of the house, there's a light switch with a timer relay in the stairwell. Connected to it are four impulse switches and three lamps. Is it possible to switch the lights to constant current, for example, to install motion…

Unknown resistance with known current in R network?

ByBrandonQuest

In the following illustration are known: Uges R1 R3 I2 I want to calculate R2. But I'm completely confused, or rather, I'm going around in circles. On the one hand, I do not know the final voltage across the parallel resistor R23, since the voltage divider R1/R23 is only fully known once R2 is known….

For Ra. the following:

Total resistance = Rges = R1 + R2 + R3 ; total voltage = Uges = U1 + U2 + U3 ;

Current intensity I = I1 = I2 = I3 ;

For Parallel connection 1/Rges = 1/R1 + 1/R2 + 1/R3 ;

voltage U = U1 = U2 = U3 ;

Total current Iges = I1 + I2 + I3 ;

You’ll find everything in the Interent.

Look.

This is the most simple e-technique for beginners.
